You seem to have your Duck's in a row guy I trust your opinion here. . .
Here's is what i'm sorta picking up as your thought's.

1. the HEI is more of workability thing not really going to effect power. . .

2. the holley 500 may over power the V-6 and dog it out. . .
i did your carb kit sugestion she got peppy on the lower end but still mushed out once the R's got up over 2 grand. . .


I got question for you can the exhaust effect power a good deal on these big V-6's ?

I got the stock manifold's ( one leak's ) blowing threw 2-1/4" single exhaust. . . Could i be losing my power on the out flow and not the in flow ? as if that's the case a bigger carb will dog it out worse ?
