i think you have your ideas mixed up. you need to do more research. and stop using the 1 to bring your threads back to the top.

what turbo do you plan on running?

REVHED

The exhaust manifold has absolutely nothing to do with whether it's draw-through or blow-through.

lol, like i said he's lost. he needs to search more and stop making multiple threads with the same question but different title.

stock CFM for the carb is 315 +-
If you were to run 15 psi boost you would need roughly twice that. (say 600 cfm)
This is clearly in the range of typical Holley carbs. A vaccum secondary such as a 3310 (750 cfm) would be likely to suit this setup since the scondaries will only open as needed. With 15 psi of boost you had better be thinking of how to intercool it or at least set up a boost triggered water injection. keep us posted on you progress. Once you get it running be sure you creep up in one pound increments of boost and do many many plug checks to detect detonation. Remember you are trying to build a performance engine, not a grenade.

The stock FC turbo manifold can be adapted to fit the 12a. There are write-ups on it, may even be in the archives. Sounds like you need to do a lot more research and searching, and buy the book on turbos by Corky Bell. Maximum Boost

If you are looking for more than 6-8 psi, you will need to do a blow-through system, with an intercooler.

Good luck.

Just so you know, stated carb CFM measurements don't mean jack **** when under boost. ie, any given carb will flow way more when under increased pressure.
