So it will really be about 8.5! Better than the older smog engines.
OP, a couple of question for you:
What cam is in there now?
What is the goal and use for this engine? Drag race? Street cruising?
The cam and maybe gear choice will change depending on this. I can think of a couple of better cam choices that will do the same for peak HP and do a bit better for low end torque, if that is of interest, like the Howards .904 optimized or the Voodoo Grinds.
If you don't care for the low RPM torque to be better than a smogger station wagon (and indeed you may not), then the cam in the 1st post is not too big IMHO.
