Thanks! Motor is a 383 with Dart Pro 1 heads and FAST efi. Turbos are Turbonetics T04B (60mm) and running a two-stage boost controller. I plan to run street trim around 8-10 psi and my track tune is 15 psi. Made about 750HP/750tq prior to reworking the hot side to flow better, I anticipate putting down around 800 which is about as much I want to throw at the original GM block but should be enough power for the street. How about you?
