@Max Capacity and @Pleides - thank you both! Yall saved me a bunch of money and headaches. Sounds like the bottom end can be used without too much trouble. I'll have to calculate the compression ratio of the bottom end (its a p2p stage 2 closed deck with callie ultra rods, cp pistons, and cleavite bearings. Any ideas on what signs of wear i should look for when purchasing this motor? I plan on checking clearances on engine deck and look at crank and cylinder walls.
