Turbo and cylinder head question.

[lilvega]

Currently I have a ford block 347 stroker in my 69 with 185cc aluminum heads making about 500hp and 520 ft lbs at the crank but I am afraid the block will be short lived so I am building a Dart block 363 to replace it. Since it is nearly bulletproof I figured why not add a blow thru turbo setup as well. I have had 2 different turbo cars in the past but they were factory setups.
I have a few questions:
#1 Should I go with larger volume heads, like AFR 205 or will the 185's be enough. This is a street car that will go the the track every few months for fun. At what point will the heads become a limiting factor under boost?
#2 what turbo for this combo to get about 600 wheel hp at 12 to 15 lbs of boost? I want a single and am currently looking at a precision 76mm but what trim? I will not run a trans brake on my c4 so I want good spool with a 2700 converter.

Suggestions?

It all depends on what kind of piston u got

Air in air out. I'd go with the bigger head.

The 185's will be plenty and be more responsive off boost. If it makes close to 500hp, at 15lbs, should make between 750-800rwhp. To make 600rwhp shouldn't take but 7-8lbs. A single 76mm will make that power and should come on strong on a 347. My buddy has a ball bearing 76mm on his stroker mod motor and it's at full boost by 36-3800 if it hooks.

I have a few options there.
Run a flat top and have mid to upper 10s on compression (then run e85) or a 23cc dish for about 8.8 to 1 and pump gas.

The recommendation I was given was to run high compression and use c&s specialties pre-programmed 6al2 box for timing.

I decided to do a f4 351 in mine.

Flat top 10:1 and boost does sound like a good mix
