tlowe, geat project, stay with it and you will be happy in the end. I finally got my 250 turbo finished (if they ever are really finished). My setup is an Offenhauser 4 barrell intake with the same throttle body ('89 Chev 350/ 500 cfm) with an adapter from Turbo City in Anaheim, CA. The turbo is a T4 from Innovative, a great bunch to work with. In lieu of spending the big bux, I used a stock exhaust manifold with a 2-1/2" tail pipe going to the turbo.
I have one of the Innovative turbo manifolds for the next project and recommend it highly. The $595 is a pittance compared to the price of a good stainless tube manifold, prox $2,500 at my end of the world. I personally built a carbon steel header which lasted about 1000 miles!!!!!
My engine manager is a computer from Injection Logic which works well but the company imploded so now I get help with it wherever I can. Fortunately, since it was calibated, I haven't needed any service.
This engine is getting some improvemets as we speak and will go into a '68 Camaro which I hope to drive to Denver for the Big Meet. Hope to see you there, let me know if you would like any pics of the '39.
