It all depends on what you want to do. I know of brand new 1250's that pumped 150-160, so compression isnt necessarily the issue. You can spend as much or as little as you want. Theres $7000 rebuilds out there, or you can do it yourself for $1500 in parts. Feel free to PM me with any specific questions. We're not doing outside engine work, just our own, so I can't help you that way, but I can help you out with some of the stuff we've learned so far, and sources for parts at reasonable cost
