What cam are you running?

I'm going to reuse the pistons. The cylinder walls look good so just going to hone them. The engine only had 42k original miles so everything looked pretty decent. I was thinking of going 30 over but that would lower compression I guess. I have the 1.70 1.44 stainless valves head milled .090. 4bbl intake with a holley 390. By what I've read online just milling the head .090 and using the factory steel gasket will bring the compression up to 9.5 to 1. You run a good time for a slant what's does the car weigh? (Mine is 2900lb)

well it may be 9.5:1 but ive seen the piston to deck height's vary from .140 about .200 so compression based off head milling is impossible at best. BUT IF it is a 9.5:1 motor and the head was done well you should be a good 125-140hp i would bet. No matter what the number is its going to be MILES better than what it was.

My 68 weighs in a 2850 w/o me last time i scaled it but ive been working on trimming the fat so i couldn't tell you. That said 2775 would probably be about right w/o ballast, race weight is 3200
