You have pics and proof of the build receipt etc....as this motor also seems to be on eBay from a unknown shop,? Who ....as it’s a rebuild obviously ..I think it’s reasonable to ask for proof , as with that build I’d hate to load it up with 15psi and it go bang,...some of us have been sold motors which aren’t what they were meant to be,,what shop rebuilt the motor pls..thanks

His number is in the post/ad. I bet if you call him and ask for the documentation, he'll send it to you.

Are you sure on that compression ratio? I'm thinking it should be more like 11.25:1 w/ those flat top pistons w/ valve reliefs and that additional bore and stroke.

Did you factor in the chamber volume?

The PRC 260 heads start at 68cc and go down in size from there, so yes. Even the L92s that have valve reliefs are like 10.4:1 with 68-70cc heads stock.
