I am building a sbo 362 70 gas block with a 76mm turbo..I am installing j&s machine full main girdle..It'll have eagle hbeam rods, forged lightweight pistons forged 330 crank 300+cfm edelbrock heads...Turbo cam victor intake and fuel injection am I on right track? Motor has over 500hp naturally with mild cast heads gotta change everything going for 650-700+....

Sounds good to me, got some better parts than my engine. I've wondered how my engine might benefit from a victor intake but I want to stay under the stock hood. What's your comp. gonna be and are you planning to use an intercooler or meth injection?

Welcome to the site, sounds like a cool project. What is it going in? Whats the rest of the powertrain?

joe_padavano

That sounds like quite a build. Personally, I'd spend the money on a DX block with four bolt mains added, rather than the girdle.

cutlassefi

How much boost? What are you shooting for for a static compression ratio? What EFI system do you plan to use?

turbodolds

Finding a DX be fun and it'll be intercooler probly go holley efi its my 82 cutlass that's been 7.29@95 thru 1/8 mild cast headed naturally aspirated streetcar...found a few issues cap and button was shot and front squirter messed up and no pinion angle all I've wanted is 7.0s or at least low 7s on motor before I go turbo...by the time I get block work done it be as much if not more than girdled gas block I'm running I'm guessing...

Well you answered one question so I'll ask the other two again if you don't mind.
Thank you.

9:1 7-9psi 650-700hp

How do you know you are over 500hp NA right now with the engine you are using?

cutlassefi

Then you'll need to make 450 or so on motor alone. Might want to rethink the 300cfm Edelbrocks, that'll get expensive and probably not necessary for your goals. If you have E85 available that's a nice alternative to running an inter cooler as well. However the Holley HP doesn't support multifuel, need the Dominator for that. Just a thought.

We dynod it I have dyno sheets I'll post vid with old wore out carb what it made...

turbodolds

here ya go they beat on her a bunch this was almost 5 yes ago..

wr1970

Cool vid. Have you ever run it in the 1/4 mile? If so what did it run?

turbodolds

no only 1/8 round here

wr1970

Good luck on your new turbo build. I hope you post progress as you build with end results. Sounds like a cool project.

So you think my heads are fine for my turbo build? 240cfm cast head#6s? I want 650-700hp but I'll have to have a $1,000.00 main girdle so I'm told

cutlassefi

For 650-700hp I'd use a 5 main halo with better center caps. You don't need a full girdle in my opinion.
240cfm heads would be fine but I'd still opt for a set of aluminum something, Procomp or Edelbrock. My point was you don't need $1500 worth of porting to try to get 300cfm. A set with 260-280cfm would be more than adequate.
And if available I'd seriously consider E85. It's cooling capacity would all but eliminate the need for an intercooler, even at higher boost levels.

I have good eagle H beam rods but forged domes and forged 330 crank with my 58cc #6s and .040 cometic mls head gaskets I'm 12:50:1..I'd definitely need different pistons I'm going alum heads would older series edelbrocks be OK done up?
