Alright thanks. That truck sounds like lots of fun. 59 sqinch and on 91 octain run real good at that weight. I'll go with the 0.26 gasket and the 64 chamber heads and see what happens. Should be around 10.1 or so. Maybe alittle less. It's in a Nova no air or power nothing. Ran pretty good with the big chamber heads. Should pick up some with the change, plus the fact of knocking 50+ pounds of the front. Thank you sir.
