Thanks for the insights jpar, I have looked at the nhra rule & yeah there's alot of extras involved, I'm waiting for howards cams to return my call & might be looking at a
[email protected] .576 lift cam for a better overall cam. Hughes told me I'd be leaving some power on the table without bumping up to 12.5 & I can get 11.6 By changing head gaskets. I was wondering if advancing the 260-264 cam 4 degrees would be fine to help the bottom end street driving? Or can I advance more like 6 or 8 & go back to straight up for the track ? Any thoughts on that?
