Thanks, 76GM, I have been told the same by several other guys. I was just hoping that it could be done safely in small doses, just to put a smile on my face when the race boat is parked. May swap out pistons if I still have the craving.
Here's couple of my small blocks. Ones a 434ci Dart block, pro-comp-1 heads that dynos at 565HP and the other is a little 383ci that makes 445 hp.
