Got my '68 400 ragtop a couple months ago. Rebuilt a pair of "62" heads, added hardened seats(one of the originals was cracked)...Crane Cam No.283901(mild...came with the car)...stock Quadrajet and intake...longbranch ram air exhaust manifolds... The car runs well,BUT... It feels like there is some power left in her that I can't quite get to. The carb seems to be adjusted properly. Nice low idle(600)The plugs are a nice light brown color. I've played with the timing a bit but, it doesn't make much of a difference. Any ideas on how to get a little more goose out of the old girl?
I'm a hobbyist. Not a professional. Don't be hatin'!
