I've done some digging but I've found a lot of conflicting info on this. Some say 140psi across the cylinders is good, some say 150-160. There have been some as low as anything over 120psi is good. I did a test on all cylinders on my car and it has roughly 120psi across all cylinders (within 5psi of each other) . It runs fine, but just doesn't seem to have the power it once did. So what is the correct "healthy engine" specs? Also, any ideas what kinda power loss I'd be seeing with what I have?
Trying to decide if I just run it, re-ring it, or completely overhaul it.

Thanks for any help

I would say a healthy stock f2t motor should be at least in the 150psi range possibly more. I re-ringed mine last year and it has 150-155 on each cylinder. I would say as long as it runs good and doesn't burn a bunch of oil. Just send it. If your not happy with it, re-ring and put new bearings in it too. You can do it with the engine still in the car. Good luck. Let's keep the f2ts alive.
