360 magnum short block

Not real sure I haven't done any measuring. Stock compression is 9 to 1 and these were supposed to be a little higher up around 9.8 . Blocked was decked some so that should help. Sorry I didn't answer your question more direct. Was gonna run a 62cc head

Knowing Rumble, he is looking for how the assembled piston/rod crank assembly: How far does the piston sit below the deck,actually measured.
