Started tearing into the /6

ok well the first thing i noticed is that it looks like dents or pits in the first pic, those would be from pinging or detonation...

second in the third pic unless you changed the angle the piston is in backwards lol... now this actually helps with HP becasue the pistons are ground egg shaped... but you have to do it on all the cyls's just not one lol...

ok since it sounds like your going to to a performacnce build you need to decide if you are going to bore it or not... (summit carries pistons for 12 bucks each up to .080 over)

you need to figure out how far the piston is on the hole with what ever pistons you use so you can figure out compression... so either you just clean up what you have or new, whatever... just find that number out so you can have the block milled X amount to increase compression to a normal number! plan on at least .090 right off the bat tho!
