im building a 383 with cc306 58mm tb 3500tci stall 3.73 11.4cr long tube headers msd 6a cleaned up 2.00 1.56 valve heads,full bolt on i want 11s @ about 116 i think i should be able to do it with out a problem but what do you think?

 

Should be pretty easy with that combo but it depneds on how well the heads flow. I have run 11.15@121mph with a 355 LT1, Cc306 and a set of Lloyd E ported Trickflows (Heads/intake currently forsale) but there are alot to making a car run quick. Later

 

yeah thats what im worried about is how well they flow, the machine shop pocket ported and did the valve work but did nothing to the runners so i gasket matched them,

 

should be fine.. i run 116m.p.h on stock heads with 306cam

like the man said theres a lot more to it than that
