Thanks, it's should be 112 then, the grind number on the cam was 312-2.
I'll hold off on the regear for now. I have no driveability complaints with it with a 4 speed and a 26" tire as long as I keep the revs above 2500 or so while cruising, below that it struggles. I used to have a 28 inch tire, but don't remember how it liked lower rpm, and it was an auto at the time.
I think ideally you are correct and a new cam should get installed, it's just not in the budget currently. I did have my eye on the Isky 264 Mega grind though. This is just a street car, I don't ever plan on racing it, so not too concerned with top end power.
