What is the norm for compression on a 327? Just wondering. Thanks

Is the 327 from a Camaro? If so, is it the LF7 (327, 210hp) or the L30 (327, 275hp)? Static compression on the LF7 is 8.75:1 I believe whereas it is closer to 10.25:1 for the L30.

I have 150+- 5lbs in each cylinder. Is that normal?

I would say, yes, that's good.

As long as your within around 10 psi of each other, you are usually pretty safe. You don't normally loose pressure in all cylinders unless the motor is really hosed.

If your not living on the edge then your taking up too much space
