The V6 oil pumps will show 60-80 psi on the gauge. In fact 67-69 GMC pickups as well as Medium duty trucks with V6 engines up to 74 used a specific 80lb gauge in the instrument cluster. I've seen what happens if you use the 60lb gauge that was for inline 6's and V8's in the V6, the gauge is constantly pegged out.
Daaaaang! That's what my big block 572 puts out!

Now I really wanna see! haha
