Compresion

[SER240Z]

I'm sure it's somewhere, but I couldn't find it. What should my compression be on my L28? I did a compression test and have 150 across all cyclinders. Is this where is should be, or how close am I to what is right?

Thanks

I'm not sure if it varies from one year to another but the FSM for a '77 L28 lists 164-178 PSI.
