Ok I am back with an update-
The 302 has only been "reamed out" with a stock setup. Headwork to take unleaded gas.A little slop at the top of the block; so machinist recommended .30 over to clean it up. Crank just needs polishing; wanting to regrind the camshaft to go with the compression boost. Need the bearings& pistons. Just got off the phone with a buddy who stated he may have a set of .60 over pistons. Is that too much?60 won't be able to take another boring? right.
I want to bump up the compression to around 9.5-1 using pump gas.
Any thoughts?
