porting performer intake

Nicks5.0 · 04-03-2001, 03:26 AM

im with the rest of the guys, dont take to much out. that will hurt velocity. just smooth out the casting flash and match up all the ports/runners and gaskets. go slow and keep a steady hand. you can always take more out later, but its not as easy to add what you shouldnt have removed, ya know? you didnt say what kind of combo you are running, but with the performer, if you think the motor is starving for air at the top of the rpm range, with the removable cover you could grind back the start of the runners a little bit and at the same time enlarge the plenum which would give up a little down low and probly help out on top, but this isnt something to consider if youve just got an intake and other bolt-ons. ok, im blabbering now...just go slow and steady and dont get greedy. sorry its so long, nick
