WAS ENGINE BORED FOR OVERSIZE PISTONS??? Then MUST have been honed or totally messed up there. You CANNOT competently assemble motors and not know if hone done/not done if rings are changed, death lies there and totally unacceptable. The start of a major FU. Not trying to be an butt or insult anyone, but it needs to be said. I would be dogging the person who did the machine work there for more information. If not bored at all then you get into the nightmare of what kind of condition the cylinder walls were in to begin with, not knowing if honed just doubles that nightmare with all kinds of bad possibility. The rings (especially moly, even worse if double moly) MUST have correct break-in wall finish or they are junk as soon as started up and run five minutes. You don't get another chance after that without new rings/walls.
There will be no exact compression number since cam timing alone advance/retard can greatly affect that, all I know is true 12/1 needs well over 200 psi, I'd be expecting like 220-230+ on a well sealed motor. Even more (250+) if the motor truly setup to get the advertised compression, i.e., decked correct for the application and proper cc head/head gasket thickness, the compression can range off a full point by simply throwing in pistons that say they are this or that number, not nearly that simple. Catalog advertised compression numbers are worthless without the motor set up to spec called for there.
