Here's the deal. Y-blocks CAN get into a cycle of starving for oil, and then have ample oil, and repeat. This only happens at RPMs about 4,000 RPMs and up. If you put a Y-block on a dyno with oil added only to the full mark on the dipstick (4 qts, plus 1) the thing is fine to drive back and forth to work. But sustained RPM will smoke a crankshaft, or camshaft bearing.

Pretty important for a Y-block to have regular oil changes, to keep "oil flakes" from building up. Gotta keep the oil return flow as good as possible.
