Just did a compression test on my 383 stroker, vortec heads. About 500 miles on the motor, I'm not sure if the rings were done correctly.... :pain:
165psi, after about 5 minutes it was down to about 160psi
How does that look? This is my first compression test.
Also, motor was cold, haven't started it in a few days. I didn't know if I was supposed to do the test with the motor warmed up or not.
With out knowing more about your engine it's tought to say if that is a good number...
Go back and do all 8 cylinders, with a warm engine and the carb opened...
let us know the results... Don't forget to disable the ignition......
With regard to Ring Sealing, would it make sense to do a "dry" test as well as a "wet' test?
What else would you like to know about the engine?
I will re-try with a warm engine in a few days, I can't do it quite yet.
