Just to make sure I have it right. With the 295+.060 307 piston in the block with a correct 250 crank you are .055 down in the hole at TDC without anything removed from the block. Is this right? I wonder if they took a little off the top of the piston because it is .060 over. Enginetech says that they do this on their pistons. Too bad we can't know what height the pistons that came out were.
