258 to bore or not? HELP
Ok, got the measurements on my bores and pistons. Needing some help to decide to bore it or just re-ring it. Called a few machine shops, they want to see the block and wouldn't give advise. Hoping JF will help!
bore = 3.752
piston = 3.747
clearance = .0025
NO ridge on cylinder, except for a small bit of carbon at the top. I pushed the piston out very easily. Pistons look ok, the tops look cruddy. No idea how many miles are on the motor, it was a transplant. Motor hat 120 PSI compression, lots of blow by.
