Old 455 had .035-.004 on the mains, 60 lb pump. Ran forever.
New engine, 60lb pump, 9/16 ball and .074 shim. Lots of oil pressure. Modified pickup with near .90 inlet dia.
I had so much pressure with 30 WT I had to put some 10-30 in just to get it below 90lbs.

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world.

Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
