"After engine repairs, I found cranking compression tests to be around 70-80 psi. That's what you get with a 6.45 comp ratio. I assume psi will go up a little after seating the new rings."

Thanks for the post. When I checked compresion in mine, the most I got was around 60 psi with my compression gage (which I am not sure it is correct but I will check some day with another one), and that was pretty even on all cilinders except for cil no 1, with cero, and cil no 3, with around 40. I will start using the car and check again some time in the future, hoping that the detergent oil plus seating of everything inside, will make it rise to 70-80 psi... but I have say that even with the 60 psi I am getting and the engine running like it is now, I am very impressed of it's smoothness and power.
