A friend of mine is having a engine built, and wants to go .070 over the stock 440 bore. I am having 2 blocks sonic checked, what is the max overbite for a stock 440 block ?
Yeah, if you like pop can thinned walls.The engine is for NHRA Stock, know it will be a custom piston. But it will have to be NHRA approved. I looked up the rules, for Stock a max overbore of .080 is allowed. Is .080 possible with a stock block ?
Thanks for the replies, dropping off at the machine shop to be sonic checked.
