You Got It Carl!   Hell of a Ring Tone:-)

Can't wait to see that one.

There is still a lot of work to do!
I need to figure out an alternator and mount + a belt drive for it. I also need to save up for the vac pump system and belt drive.
These items can wait until after the engine dyno tuning next month though as the engine dyno guy can hook me up with whatever power I need to run the water pump and the MSD 7.

I was thinking about running twin race batteries and no alternator.? From what I unerstand my MSD 7 can draw 20 amps, I know my fan and pump will draw 17amps, I know my nitrous system could pull 60amps when pulsing 4 solenoids for a 500 shot.

And when I pull back into my pit I will want the pump and fan running until the engine has cooled down. So maybe 10-15 mins ?  
I have not made up my mind yet. But I am veering towards an alternator at this time )

Quick Update !

I have managed to lose one of my Holley 600DP carbs??

So in the pic above I had used an unknown spare that I bought for peanuts as a spares carb. The guy said it was working on his road car and I have no doubt that it could have been. But after stripping and dipping in the ultrasonic cleaner I discovered a crack in the main body which has been badly welded. Also one of the mounting lugs has been broken off and welded back on, and its now cracking along the weld. And when I removed the front float bowl the plastic breather was missing. And someone had blocked off the hole in the jet plate with liquid metal?  So this is still just a spare parts carb now. I'm now doing some research with Holley / Demon / AED etc about the price for a pair of matching race carbs made to suit my engine build.

My reason for looking into new carbs is that when I did the calcs for my new 383 build, the numbers showed that even at 100%ve at 7500 rpm the engine will only need 750cfm (ish). So with two 600cfm carbs the velocity through the venturi's will be lower than ideal. My worry is that the low velocity will not give me good atomisation of the fuel. I believe that modified boosters can be fitted to cope with the lower signal which will give me what I need. Eventually I will be putting the nitrous plates back on and that will lower the airflow through the venturi's as well, but I can compensate for that with extra fuel on the nitrous system as I have done in the past by using my lambda readings as a guide.

So 2 new matching carbs built to suit my engine should be the best way forward I think ?  This will set the engine dyno day back by 3 months but so what !!  The car will still be ready to move under its own steam next July as planned I think. Its been off track for 2 years now so another 8 months wont hurt. PLUS!! As I've got all new stuff from pan to scoop except the carbs it seems a little rude to not fit new carbs eh

My SBC friends are convinced that one I get the engine dyno tuned and fitted it will run back in the 9's just on the carbs as they say it should make 600hp on the engine dyno. ?

Only time will tell eh

Awesome build. You are an inspiration.

I get the impression that it's not unusual to run dual Holley LIST 4150 390 CFM side-hung double-pump carbs on a dual-quad configuration. 780 total CFM.  I love the look of a dual-quad setup.

Hey, Perry! Check out the Quick Fuel 450cfm. Two of them would work good.

Thanks for the comments guys!

I am now having a pair of AED 650 carbs custom built and modified for my application. The main reason for this is that AED was the only company to actually reply to my request for help.

I have been having email comms between myself and John Dickey and Jeff at AED for the last week so they could come up with a solution for my needs. In order for them to provide a solution I have had to give them all the build specs of the engine + rear gear and tyre size + a lot of other info about the engine and drivetrain + the fuel I will be using.

Long story short!!

I'm having a pair of AED carbs made to suit my exact build spec for the same price that I could buy a pair of Edelbrock 500's here in the UK ?

4 weeks and the carbs sholud be here in the UK with me so I can get them bolted on and prepare for the engine dyno

Regards
Perry

Glad you didn't go with the Edelbrock carbs.  They are fine for a cruiser, but I do not consider them to be a carb for a race engine.

Haven't heard from Perry in a while. I asked about him on the V8Owners board also. I found this picture over there:

Yeah, been patiently waiting for an update on his new engine.  Hope all is well.

Perry has a Facebook page. Maybe someone with Facebook could try to contact him?

He posted today over on Martyn Harvey's MGB V8 Conversions Facebook page.

I told him he was missed here.

Thanks for that.

Jim

From Perry:

I will catch up asap Carl. New laptop, windows updates and family problems have kept me away for a while Dude! Pel

WOW!!

My last post was in November 2016??

Sorry folks.
Please bear with the following.... It does get better !

Mum got ill and we spent most of 2017 caring for her. She lost her fight eventually and we buried her on 22nd December 2017.
Most of 2018 was a bit of a blur with trying to deal with losing Mum and sorting out her estate, and me working pretty much 7 days a week due to demand. My workload had taken its toll, and by Sept 2018 I told the boss I was taking December 2018 off work. This gave me something to look forward to I must say. Then in October 2018 Baby Bro announced that his weeks of suffering with weakness and general lack of energy that his Doctor told him was "just a virus, take these pills and rest up" turned out to be Leukemia. A.L.L type which is nasty. Baby Bro has been having treatment since then and at the moment the prognosis is GOOD!!  He is fighting. The Chemo and blood transfusion's + platelet transfusions + all the other drugs he is taking seem to be doing the trick so far. All of the family took blood tests and it turns out my wife is Haplo positive as a match for Baby Bro's Bone Marrow transplant  That will happen in the future when he is ready for the transplant.
I spent all of December doing DIY around the house and had 2 days on the car. I actually had my first few days of December lazing around the house and sleeping mostly. Then I woke up and fixed my heating and hot water systems in the house. Built a new Gazebo on the decking for next Summer. This was after I laid a 15ft x 15ft decking base for the gazebo. And tidied the rear garden. When I sat tidy. I mean 2 x 8 cubic yard skips full of crap  

I have to admit that returning to work on 2nd January 2019 was hard. I had no enthusiasm for work, but I had to get back on the horse. While I was off I had two large enquiries come in which the Boss held up until I got back God Bless him.

I have spent the last 2 weeks working furiously on getting these projects specified and ready to quote. I don't really like doing projects over £100k. But these two are working out at the moment at around £450k each. So I have to keep my game head on and get these jobs sold in the next month or so. I'm sort of happy, because if I get these jobs sold I can kick back on these jobs for 5  months and not have to manage any other works until they are complete.



SO!
That's all the Doom and Gloom stuff over chaps.

Now its Car Time!  

I promise to keep this part brief........

The new Dart based SBC 383 engine and the old tranny is in the car.
I had 2 days of woe with oil pressure and oil pan issues.... All sorted now.
The new engine cranks over with 45psi of oil pressure with the plugs out.
New MSD Digital 7 now fitted and working. After 12 hours of getting it fitted and working out Comms problems between MSD and Laptop.
No Zoomies made yet. Fuel system parts are now in the shop ready to fit.
So last week I fitted some hoses to the carbs and filled them with a measuring jug and a tiny funnel.
God Damn!! She fired up in no time flat.YIPPEE!!
It was only two short bursts as the cooling system isnt finished yet and she was dry.
But it ran, and it sounded nice!

This weekend I will be finishing the new fuel system. Next week I will finish the cooling system. Then I can take it on the trailer do a lonely road in the country nearby to fire it up properly so I can bed the rings in, check for leaks, check oil pressure, check fuel pressure, keep an eye on the cooling system and warm it up properly. This will be me + at least three race buddies.

That's enough for now. I will post some pics and vids asap.

Thanks for thinking of me guys!

Regards
Perry

Sorry about the low res vid folks!

It made me laugh when the guys in the VW shop next door cheered when they heard the engine start

Fast forward the vid to 4 mins. The rest is just waffle about the MSD and swearing to be honest.

That is a badass sounding 383

Wow.  Hope you can hold it on the strip!

Perry, Glad you're back! How did the Speedway motor mounts work out for you?

Wow, really enjoyed that video! Very, very cool project!

Hi Jim!
The motor mount was perfect. I just had to shave some off the bottom to clear the steering rack. Then I added my two old steady bars from front of the engine to the inner wing and rear of the engine to the bulkhead.

The rear steady bar didn't even need adjusting. It bolted straight onto the Brodix head. The front steady bar just needed a hole enlarged in the old MGB mounting flange to bolt right on as well


I have spent so much time and money on this 383 build that I hope it will at least make 500+hp on pump gas. When I have tried that I intend to use race fuel and more timing to see what it can do.  

I am still trying to convince my friend Martin to let me onto his 1000hp Dyno with Zoomies??

Quick update!!

Cooling system now finished and filled. Water pump power supply fitted and working. I have to say that I was surprised at just how quiet the big Moroso electric pump is?

Next job is to fit the puller fan to the radiator and wire in the existing fan cables via the existing electronic temp sensor in the top hose.

I found that the tunnel ram manifold does not have a thermostat by pass. The new thermostat did not have a jiggle pin either. So I drilled three 5mm holes in the stat flange. This was fine to get the system filled and water flowing. I may just remove the stat and fit a restrictor disc though?

By manufacturing a custom bottom hose, I found that this will foul the alternator belt. So I took the alternator off and put it on the shelf. I will now run on batteries only. I will buy a pair of Excide 450/ 900dc batteries and buy the charger to go with them.

This actually means that I can replace the dished crank pulley (that I borrowed from my friends 350 SBC Volvo engine without him knowing) so he wont have a shock when he lifts the hood in the near future  

He is too busy with his Ford Pop Mopar project to even look under the hood of the Volvo 760 avec the SBC motor.

I have to work next weekend and then a week of nights on a project for McQuarie bank in the UK. So maybe the weekend of 16th and 17th Feb will be more MGB stuff?

Hi Guys!
Cooling system leaked water from the inlet manifold gaskets. I removed the Mr Gasket cheap cardboard gaskets and fitted Felpro.
They leaked as well.
Then I figured that the front and rear rubber valley seals were too thick.?  So I fitted new Felpro gaskets today and used RTV sealant for the valley seals, and then gently pulled the tunnel ram down on the bolts. I will go back to the workshop hopefully on Sunday after work to do the final torque down and then see what happens?

I seem to remember the manifold bolts needing 16ft / lbs?  Is that right!  I will look in my books to confirm if any of you cant tell me?
