I'm going to my storage unit to see if I can find some markings on the pistons to see if they're over. The receipt from my machinist up in Portland is long gone. He set it up for me as kind of dummy proof and built for reliability/longevity vs. power. I've also got a box of fasteners and the original cam that came out...not sure if it's worth salvaging or not. I'm pretty sure it was bored out a bit, the camaro it came out of had over 80K on it.

thx
