Compression check 93 k1500

I am pulling my 4.3L out of my 93 K1500 and thought I'd check the compression since it's been running kind of rough lately and I've been to lazy to work on it when I'm pullin git out anyways. So I took compression check and was getting around 150 (psi?) on each cylinder. Is this acceptable? I have no idea what it's supposed to be on this engine pre factory specs. Anyone got a clue? Or is anyone in the market for this engine or the attached tranny? I'm putting in all new gear so I dont have much need for it accept for maybe a complete rebuild and then put it in an s-10 or blazer I guess...

150 psi is fine as long as all are within 20% of the same reading.
