Accuracy of guage? A fresh rebuild needs 50 weight? After break in, I run Amsoil 10-40 w/high zinc. Lots of opinions here, all over the map. Good luck. My guage usually pegs at start up, then drops some. As long as it stirs, I drive it. Any noise?

How many rpms does it drop from idle when you put it in gear. Pressure drop seems somewhat excessive, but not sure I'd worry to much about it as long as you're carrying pressure when it's hot.

I see nothing wrong with those oil pressures. What are you worried about?

Oil pressure sounds good. 10psi per 1000 rpm. Mine idles at about 20psi with .003" rod/main bearing clearance.

Seems a lot of people believe they need 70+ pounds from idle to redline. Some myths die hard...
