When I say "Scrapped" I mean sold :)

Despite all the work I put into the block such as a rehone + decking + line boring + a full clean in a parts washer + new cam bearings being fitted. I decided that I wasnt happy with rust nodules I could see on the outside of the liners. This engine had been used in salt water in a speed boat. So i moved it on and have now bought a brand new Dart SHP race block. The new block should be back from the machine shop next Friday. I'm having it bored out to +30 to take my new forged stroker kit + a full balsnce of all the new rotating parts.

In a few weeks I'll have some time off work to start the build!

I was hoping to roll the MGB out at Retro show at Pod this year but I've put the project back another 12 months now so i can be sure to hav eit ready for July 2017.

No point in rushing now I think. And with another year to save up I reckon I can buy some more trick stuff for the engine to make it good enough to run down into the 8's on the 1/4 mile without being stressed like the old Rover V8 was everytime I raced it ?

That must have been a deep breath, big decision time moment, not to mention extra cost implication. Post some photo's of the engine when you get something to show.:tup:

Well Pel, that's a bit of a f**ker. I thought you would have been well on your way to firing the beast up....I know you were having issues with the supplier and other things, but after all your efforts and the change to SBC this must be a kick in the goolies.

Sorry to hear this, mate. I know I cant help (unless I volunteer the T engine!!) but you know where I am.

A little of tangent,but how's your old engine going ?
IIRC it was going into another MGB

The old Rover V8 engine has been rebuilt at a cost of over £2k to make it as new and it went to its new owner last Xmas to go into storage in readiness to go into another MGB GT :)

I needed to be bold on this decision mate. My old SBC will no doubt make a great road engine but I was worried about loading it up too much.

At last!!
The new block has been tweaked at Knight Engine Services. The rods and pistons have been weight matched and the crank balanced.
My parts collection is building nicely.
The list of parts I have so far is:

1. Dart SBC race block with priority oil system and thick bore liners
2. Eagle Forged 383 stroker Crank
3. Eagle Forged Rods
4. Mahle Forged pistons
5. Brodix Dragon slayer 225cc heads
6. Edelbrock Dual Quad tunnel ram inlet manifold
7. MSD Digital 7 IGN system
8. Comp cams extreme energy roller cam kit
9. Comp cams magnum pro roller rocker kit
10. Noisy cog drive for cam instead of a chain kit
11. Fluid damper 6.25" SFI crank damper
12. MSD 6.25" trigger wheel kit
13. Twin 600dp Holley's for side saddle mounting on the tunnel ram + side saddle linkage kit
14. Dual quad shotgun scoop
15. Moroso 8" deep trapdoor sump pan
16. Stock SBC oil pump and drive with pickup to match the oil pan
17. MSD billet dissy
18. A pair of SBC Zoomie exhaust manifolds
19. Moroso race spec electric water pump
20. Misc parts like old skool original M/T rocker covers + polished ally timing cover + one piece sump gasket + one piece rear oil seal to fit the 2 piece rear seal crank cap + a host of othr small parts thart I cant remember??

Thats all i can think of right now. But I will be looking at buying a Moroso triple rotor belt driven vac pump + a set of pulleys for this and an alternator.

I think the part list is now at 85% but there will no doubt be a large list of other small expensive parts like bracket kits etc ?

I'm happy to be well on the way with this engine now for sure.

I'll get some pictures up asap.

Regards
Perry

Weekend works are off the scale again. Between my summer holiday, family weddings + 1 weekend at the end of August as a Car weekend, I'm booked now to the end of September?

So I'm paying a mate to get the core engine built to my specs in his garage... Yes!! I'm actually paying someone to do my Hobby for me at the moment :)

I'm trying mate.. :) I'm now doing night works during the week to do weekend jobs that I have no weekends left to do this year?

I'm a bit miffed because a lot of my mates are already at the Pod today until next Monday for the Main Event weekend :(

mgbv8
21-06-16, 08:04 PM
Bloody Nora!
That last post was nearly a month ago ??

I'm now not sure where I got up to last month so here is an overview............. The new Dart block was cast to accept a 383 stroker kit with stock rods. But I got bigger rods and have had to clearance a bit more metal away. Thats all done now so the crank, rods and pistons all go round and round as they should. And everything clears the low base circle cam. I have to admit that this DART shp block is one hell of a strong casting. Its got so much extra metal that when my mate moved it and his BBC block he said they were similar in weight??
I'm not sure if I mentioned this before but I have decided to get the engine built and put it on an engine dyno at Peter Knights engine shop. I figure that tuning the enigne before it goes into the car is best. Peter says that the cost will be £400 + oil and fuel + vat. And its whole days work. I think thats a No Brainer really? It will save me many many days on track doing soft runs and data logging + tuning. If I spent 10 days on track setting the engine up (which I could easily do) that would be £350 in track fee's alone without fuel + food + tea and coffee ;)
I'm now about to buy my last parts which are oil pan and lifters. The comp cams extreme lifters are £500 odd so the oil pan will have to wait until late August after my holiday. I culd buy all this crap now but I would rather spend 2 weeks in the Sun with my wife and Grand Daugther before I get back to the engine. So i just spent my engiine money on a Summer Holiday :)
I wont bother buying the Vac pump system for the engine before it goes on the dyno becuase I know that the Vac pump setup will just add more power. And the Moroso Vac pump kit is going to be about £900 I think. So i need to get that bought after the summer hols but before I need to staert buying Xmas presents ;)

Hopefully the engine will be assembled and ready to go on Petes Engine Dyno in September this year... ish ??

I'm hoping for over 500hp on the carbs before I add any gas?

Ho Hum!!
Back from 2 weeks in the Sun to find that my mate "Slingshot Mike" has got my new block almost together for me :)
I was deciding what colour to paint the Block but Mike made a decision for me. I told him I didnt want Chevy Orange in my black engine bay. I told him I would prefer a bare cast iron finish but I didnt want it to end up going rusty red. So he came up with a solution which i really like. A clearcoat sealer + a puff of small metal flake + a clear topcoat. I think it works very well to make the block look like its been wired brushed to a very clean condition ? This pic was just before he loaded the block.

The carbs are on the coffee table in the lounge awaiting a full overhaul ;)
I will be at Mikes after work on Wed to bring the engine back to the Tingewick workshop so I can continue playing with brackets and engine mounts.
Mike and I will pop over when you need us G. His season in Comp ELiminator is almost over. And he's hitting the 8's hard with the new cam setup. BUT!! he has to shift at 10,000 rpm to keep on the power. 9700 rpm and the engine will bog :( Hr is well and truly into SBC R&D now with this old block ;)

Blimey!
Where dd those 10 months just go?? Family, work and more work + a problem with the SBC oil priming tool i bought ??????

I'll Rewind a few months. The engine never made it to Pete Knights. Pete was a Diamond with me having delays. So I decided to push on and get the engine into the car when I had a free Sunday. The new engine cradle had to be cut to miss the steering rack. I bolted the tranny on and lowered the lump in. First problem was the starter motor. I had to remove it to miss the chassis. But when the tranny was fixed into its existing mounts and the prop dropped on. The new engine mounts sat directly over the chassis rails each side RESULT !!! When I added some spacers to make sure the engine sat level. I couldnt get the No8 plug lead on as the plug was facing the steering shaft. After many discussions with mates about fitting extra UJ's and making a new re routed steerring shaft. I decided to put 40mm spacers under the engine mounts :) Now the plug cap fits with 2-3mm clearance above the steering shaft :) Then i ended up working 7 weeks straight which was a bummer, but it paid for next years summer hols :) Then we got the workshop clagged up with jobs which meant the MGB got blocked in for several weeks. No biggie as I was working weekends again. But I did manage to get one of the new FG doors fitted which was a mare! I'm not looking forward to the other one? I was going to attempt the Lexan windows myself, but Doug Smith at MG Motorsport said he will do them for £70 each + vat. I just need to make card templates. I have cleared out a lot of wiring and piping I dont need yet, as I'm not using Nitrous until the car is maxxed out on the motor only next year. The new custom carbs from AED look the nuts I must say. The dual quad side mount linkage kit became a source of some amusement to the lads. I ordered the first kit wrong. It was the right kit for the carbs, but it had the wrong swivel mount for the inlet manifold. I had ordered a BDS manifold kit. So I went back on line to Jegs and ordered the correct kit for the SBC tunnel ram manifold. When I got to the payment page the pc froze. So i rewound a few pages and started again. I'm now guessing that most of you know what happened next?? YEP!.....TWO kits arrived :)

I now have a working linkage kit, and it only cost £470 for goodness sake ! But I have plenty of spares :)

I have now booked every weekend between 26th November 2017 and 20th Jan 2018 off to work on the car. So I'm hoping that the car will be fired up in Feb 2018.

Pics to follow when Photobucket wakes up???

Life has to move on though eh?

For the first time in 4 months i went to the workshop and spent an hour with a few cuppa's looking at the MGB again. I saw my list of jobs to do still sitting on the windscreen. I saw condensation on the brand new engine. I saw the roof of the car thick with dust....... I was with a mate who's Mopar 360 Ford Pop was also in bits. And we decided to aim for the Mopars at Santapod at the end of July ths year for us both to be back on track:)

I guess I should update this thread eh??

As I'm such a silly old Fart I don't even remember if I updated my shit about the new engine anywhere on here?

I thought I had?

So!
40 year old SBC block scrapped. I bought a brand new DART SHP block. I bought Brodix 225cc heads. All the other bits inside are forged. Carbs made for my spec by AED. Shit loads of other stuff inside + lots of goodies bolted on the outside as well :)

long story short. The engine ran fine today for the first proper warm through. Its an 11:1 cr lump with a simple twin carb setup. I fired it 5 times today until the carbs ran dry. Fuel system not fully fitted so I filled them manually.

I'm happy with todays results after 4 years of not hearing an engine run in the car!! More work to be done soon.

Pel

I actually got the MGB out for shakedowns. It wasn't pretty. It wasn't fast. But it came home in one piece.
it was at the Retro Show weekend at the Pod.

I got there 1pm on the Saturday because I had to work in the morning.
The RWYB pit area was pretty small and I could not get in.
A Marshall told me to park on the grass by the bogs? I told him I cant put a race car on axle stands on Grass!
So I found room next to the Café and rocked up there.
We fired her up on the trailer for a good warm through and found a sump pan leak. 6 hours later that was sealed and we moved to a space by the Bogs as someone had gone home. A little more testing before 8pm saw me with no reverse gear?

We got that sussed and fixed at 7am on the Sunday.
Everything seemed ok so we got a first gentle run on track. I wasn't going mental and clicked off a 12 BUT I shifted from 1st to Neutral due to muscle memory as the box is now a REVERSE shift pattern :)

All seemed ok after checks, so on the 2nd and final pass of the day I gave it the beans off the line. I ran 1st gear out but the 6000rpm shift light didn't come on? so I shifted to 2nd and it still didn't come on as it was stuck at 5000 rpm. I hit 3rd and same again. It just went flat at 5000 rpm? The pass was a high 11 seconds so not that fast.

Back to the pit area and me and my Son both heard a clacking sound above the noise from the Zoomies at idle. So we shut her down, put her on the trailer and went home.

Fast forward 6 days and we had her in the workshop. The clacking noise was no2 cylinder inlet valve rocker loose as hell. Luckily not loose enough to drop the push rod thank goodness. Its the first time I ever had a tappet clearance of 5mm.

We got that sorted and locked down and then tried to figure out why I was stuck at 5000 rpm. It turns out that I was racing on the launch rev limiter.
This is my fault for not knowing enough about the new MSD Digital IGN system. I have had time to figure this out now and am ready to re programme as required with the help of a couple of mates who know the MSD D7 quite well.

As soon as I hit 100mph I had bad vibration and steering wobble. I eventually realised that I had fitted Front runner tyres to new rims and had forgot to get them balanced. They are now balanced and re fitted.

The last job I did before the car was laid up in Sept 2014 was to fit new brakes all round. But the braking was lame on track from only 107mph. I found that both of the new (4.5 year old) rear brake cylinders were seized. New parts now on order.

All in all my visit to the Retro Show was good. We discovered a few problems that are now being dealt with. That's what the Shakedown is all about eh?

We will roll her out again in a few weeks at a RWYB to test again. Hopefully I will get it ready to run harder at the Mopars in August ?

The plan is to max the NASP engine out on pump gas first. Then change to race fuel and add some timing to see how that does later in the year.

If that doesn't see the car back into the 9's again it will be time for new low comp pistons and Nitrous. The whole idea of this new build was an 8 second timing ticket.

Its taken over 4 years to get to the point where I could actually sit in the seat and drive the car. After the first test pass that loss of time was erased by the Big Cheesy Grin on my chops when I drove the car back to my pit area to meet my Son / Crew Chief.

I'm at the workshop tomorrow so I can fiddle with re programming the MSD.

Then I'm at the Pod on 20th July to see if the alterations work. Then back again at Pod for the Mopar Nationals if they will have me back so I can give it full nasp beans off the line.

I'm just waiting for a reply as the advert says American Muscle only? Last tie they l;et me in because the car was pre 1980 with a V8 and rear wheel drive. The last time I was at the Mopars I had a great weekend. I was only supposed to do the Saturday. But when I got home I asked the Wife if I could go back on Sunday as it was so much fun. This resulted in my most hilarious video of all time in Slo mo. But also my most spectacular vid. For some reason I was flustered and didn't do my usual pre launch setup on the start line. For some reason I launched from idle instead of my usual 1800rpm for a foot brake launch. When I floored it the nitrous cut in but at way too low rpm. The engine complained. I pedalled it a couple of time and then thought Sod It! Lets go. So I floored it and still ran a decent time :)

I figured out the MSD issue. I will ground the launch rev limit wire and the burnout rev limit wire. This SHOULD clear those items so I can race with the 7500 rpm rev limit next time out on the 20th. I need to iron out these niggles before I go to the Mopars for proper testing. I have been accepted to run at the Mopars this evening :)

I have a new plan now !!

I have wired in the Trans brake system / Launch rev limit. I will be at the Pod 20th and 21st now as I have been asked to do Demo runs at the BMW show on the Sunday.

We will hopefully have the other car with us on the Saturday as well. This is my mates 434 CI SBC Landrover ! And we may have a TVR with us as well?

I may wire in the burnout rev limiter if I have time next week. I have no idea what will happen next week when I run the car. But it better be quicker than the slow ass 11 seconds I did last time out. If anyone wants to come and help or watch that would be great. I will be running on Sunday 21st as a demo car at the BMW show. After not racing the MG for nearly 5 years I feel like a rookie all over again :)

The engine didn't run as expected last Saturday. It was still bogging at 5000rpm on track.
By 7pm last Saturday I was ready to throw a petrol rag under it, light the fire and walk away.

But my Home Boys in the pits got me to wind my neck back in.
The first test pass on Sunday was 11.9 seconds ffs?

We spent many hours working out the gremlins in the MSD programme. And then we found a way to fool the MSD. We re programmed the Launch map to the same as the Race map.

The second pass dropped from 11.9 seconds to 10.4 seconds ! So I think we had a handle on this issue now.
The following test runs went from 10.4 to 10.3 and then to 10.2 seconds. Then we ran out of time for Sundays demo runs at the BMW show.

So I think we are now on track for more test and tune at the Mopars at the pod to see if I can break into the 9's again on just twin carbs?

Mopars report !

The end result of the Mopars weekend is that the car is coming off track until next season now.
Despite sustaining some mechanical damage, the weekend was a roaring success for sure. I now have a long list of things to get done ready for next year. Its mainly suspension upgrades and engine mount upgrades. Along with definitely fitting the wheelie bars and Chute.

Learning about the MSD was a bit slow for me. But with help from friends I slowly got my thick noggin around it. The Demo runs at BMW show were all low rpm trans brake launches. Although the converter is 4500-5000 stall. The 10.2 pass was with 2500rpm on the trans brake and with a chunk of timing taken out for a couple of seconds.

At the Mopars I decided to start increasing launch rpm. The first few runs were ok but getting a bit more lively off the line.
I did get a rear view vid of the rear axle (thanks to Ian Blackett) with only 2000rpm on the trans brake. The info vids are all Slo Mo, as I prefer them for this sort of thing. The vid of the rear axle, although Slo Mo, made me think that the poor rear axle was just sitting there minding its own business, and then someone crept up behind and blasted a Klaxon horn :)

The vids here are the important ones for me.
The first is the rear axle.
The second is when I had 3500 rpm on the trans brake to actually give me a lively launch.
The third run video was a bit of a cock up for me to be honest.

The third video brings back shuddering memories from sept 2014 when I broke the Rover good and proper due to me NOT doing something I should have done with the nitrous controller. That's another story for another day because it IS complicated!!

So!
The third video of my last run for 2019 was the result of me cocking up the launch programme. My two MSD experts could not attend the Sunday. I pulled up a map on the laptop. All I intended to do was add 4 more degree's of timing on the RUN map from 4000rpm to 7500rpm which I did. HOWEVER! The map I pulled up was a test map with all rev limits set to 7500 rpm. And when I pressed the "Transfer from PC to MSD" button. My fate was sealed :)

I got staged and then pressed the T Brake button. When I floored the pedal I could hear the engine revving way to high, so I looked at the tacho and could see about 6400 rpm. I was in full stage with the other car. I panicked, I backed off the pedal to try and bring the rpm down to 4000 and at the same time I was sure I saw the ambers come on as I looked up. It must have been a reflection or something? So I let the button go and all I could see was sky! As the car hooked it just climbed instantly . I came off the pedal and then back in to try and soften the landing. That didn't work! But as it bounced after the landing I was back on full power and it started to climb again. I cant remember how many times I pedalled, but I didn't want to abort the run so I gathered it up as best I could and pushed to the finish line with no time showing but a fairly quick pass despite being on and off the pedal for a while. The engine sounded smooth and didn't seem to miss a beat. But on the way back to the pits I could hear an occasional POP from the exhaust? So I pulled it to 2nd gear and just chugged back at low rpm. I got back and left the engine running. Nothing really sounded out of place to be honest. But when I did my usual thing of holding my hand above each zoomie pipe, number 8 was cold. I normally feel a strong hot pulse from each pipe, But number 8 was lacking in puff and the exhaust gas was cold. This is when I found that the broken engine mount had let the engine drop on one side by about 10mm or so. When I fitted the new engine I had one main problem. That was number 8 plug fouling the steering shaft. So the engine was raised at the front until I had the plug boot on with about 3mm between the boot and the steering shaft. Number 8 plug boot had fouled the steering shaft when the car landed hard on the launch and the plug insulator was broken. Although this ended my race season for 2019, I was sort of happy that she ran so well on 7 cylinders, and the vids gave me valuable info for the work I need to do for next season. I will try to attach a link where the last cock up pass can be seen in real time.

Regards to all!

daja vous mate....

At least its only a engine mount. Now you are going to worry about the rear end... cant remember if you are running a spool?
I remember you did a LOT of work on the Salisbury a few years ago but dont know what it will take, especially on TB.

Looks like you'll need a 4 bar rear to stop that axle rotation.
That will be even more efficient at lifting the front up :)
Wheelie bars a must :tup:

Gerry!
I am running my original MGB V8 3.07:1 ring and pinion gear in the diff (44 years old now) with a Ford 9" spool modified to take the Crown wheel. Then I have 31 spline shafts to deliver power to the slicks.

As I had 2 weekends to test and tune before the Mopars I got more confident in hitting the rear end on the trans brake. So far I am happy that the combo WILL flip the car over backwards if I kept my foot in. I will no doubt break the rear end in the future. But until that time I will concentrate on that 8 second ticket.

Hi Phil!
I intend to retain the cart spring setup at the rear. I will re tune the slapper bars to work with the wheelie bars. My idea is to make the slapper bars lock up very quickly to stop axle rotation. And then let the wheelie bars do their job. This will take a good deal of test runs and slo mo vids I think. I may think about fitting ladder bars as well?
