i have a .040 over 413 w/ ported 452 heads, a purple shaft 292* .509 lift cam, and an RPM performer intake i want to put in my 65 ply. i have a set of unused hedman shorty style headers for RB's in the attic. i would like the clearance and all around ease, plus the fact that i already have them is a huge plus. but i'm wondering how much power i would be giving up over a set of TTI's or other full lenth headers. this car is going to be driven quite a bit and i dont mind giving up a little for the clearance, but i dont want them to be my engines bottle neck either. anyone have any experience w/ them? thanks Sean Dietz ____________________________________________________________________________________ Looking for last minute shopping deals?
