Thanks for replying to my cylinder heads post. My 360 is bored out .30 over zero decked 10.50 compression. Stock crank, comp 268 cam, Keith black 107 pistons, j heads, edelbrock air gap with a holly 750 and headman headers. I’d like to get to 500 hp but I don’t want to lose the every day driver reliability I have now. I’m not worried about the money. I just want quicker if I can get it.
