87 octane? Not likely, and besides...you don't want to run that camel piss anyway. The grade fuel doesn't have all the "boutique" additives that the oil companies put in their premium (92 octane) fuel.
Roughly 20 years ago I ran some 6X-8 heads that measured out to 98cc, which I had machined to measure 92cc. With a .030" overbore, standard Fel-Pro gaskets (1016 if memory serves) and a .000" deck height I was right at 10:1-CR. It ran fine on 92 octane, but I made sure to stay on top of the tune always.

"Cliff , No I wish I would of , I just wanted to get in the car."
Understood and the drag strip is your dyno if you have good traction. That engine combo would EASILY make 1hp/CID. We've made 440hp with RAIV cams in similar combo's without any porting of any kind. My first 455 made 455.4hp with nicely cleaned up 6X-4 heads flowing 232cfm and the Crower 60919 cam. I'd estimate your engine would be closer to 480-500hp with that much cam and 250cfm heads.......Cliff

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
