Ok heres my setup, or will be my setup very soon I should say. 430, .030 Bonafied 10.0:1, TA 413 Cam 1231109 heads, Bowl Blended, and some port work stock valve sizes Poston S-divider Hooker super Comp Headers. 1 3/4" primaries, 3" collecters Original 68 q-jet, built to 71 Stage 1 specs. Probably going to do a whole lot more tuning with it this year. I'm hopeing it will be pretty peppy. As far as the car goes, I'll have a th350 with a 2600 stall 3.42 pozi, Boxed rear control arms, otherwise stock suspension. Give me some guesses. Hopefully I'll break into the 12ss. 12.5 is my goal by the end of the summer. I will be swapping in a 4 speed sometime early summer... Let me know :beer :beer
