Just trying to help is all.

no i said and in the past said it is. BUT i played with a 572 bbc that was low and did find that the hole in block was about 005 bigger then the oil rings could hold . played with it did find thicker O rings well that did not help much maybe 1.5 pounds was nothing the engine was set up loose that.s all that was over 10 years ago with many bottles of NOs thru it and getting the hell beat out of it in the muds pits. after the piston came apart crower billet rod cut threw the piston wall this block now back in the shop i did check lifter bores @ .0003.5 on the lifter to bores and the the rods and mains over 003.5 this did added to the lower oil presure. with this 383 two blocks doing the same thing ? yes checking the Dist size at that point may not be a bad ideal . have to start some were but 8 or 16 lifters will pass more oil
