78z engine question

I just ran a compression check on a junkyard motor in a 280z. The compression was 160 on the low end and 175 on the high. It has the N47 head. Would this be a good one to swap into a 240z?

Re: 78z engine question

I would swap on my Ztherapy SU's. The thing is that I thought the 78 z's had dished pistons. I thought dished piston motors had compression readings in the 140's not 180's.
Can anyone clear the air?
