I checked the compression on my 1970 1/2 ton SWB 350-4 bolt today and every cylinder was between 120-130 psi. The manual states it should be 150 psi. My question is, should I rebuild or get a new long block, or leave it as is? The motor is a bit tired, and I'm getting ready to repaint it, so I'm debating if I should change it out before painting.

Any suggestions?
