Great information and thank you for sharing it with us. What did you do to button the bottom end up? Can't believe a camshaft that large and it still only peaks before 6500.

I felt the 3800 lb. car should have run 11.80's if the hole in the torque curve wasn't there. Actually the car was pretty low compression but it impressed a lot of people for a completely stock bottom end. Keith
I was thinking that should have been a mid 11 sec combo...but like you said w/ an older low compression shortblock and a tight converter, it still ran good. Really nice gains w/ the new combo!

Keith, you are a stud.. But those yellow wires hurt my eyes. Do you still have it on the pump? I'll send you some wires.. Will the 135 degree boots work on all spark plugs? Are those his headers? Thanks
LOL...HP would have surpassed 650 with some REAL plug wires! Just love the spark plug boots...cute.
NICE build and awesome power with garden variety parts in the right hands!

First day at the track along with a new 8" convertor he ran a string of low 10.60's with a best mph of 127.2 60' times were really soft, 1.55 range driving it like his old combination. The mph should be good for 10.40 something I figure. Keith
Any idea what the track elevation is, or what the air was like at that time?
