Yes do not run the engine without the hole. I picked up a 455 a few years ago as a fresh rebuild with scrap cam 40 minutes of running with no hole in the plug. This engine had all the right parts but was probably built by a Chevy guy so ended up saving a bundle on machine work.

How important is it that there be a .03 or .04 hole drilled in the aft oil galley plug for extra dizzy gear oiling like Joe Mondello insisted? Reason I'm asking is the crate engine I just picked up doesn't have a hole in the plug as it was built from the '70's book. Should I pop the plug and drill it? Thanks in advance, Woody




Flat tapper cam break in is a crap shoot now without zinc and knowledge about proper cam break in procedures. I know many builders that won't put an engine together unless it has a roller cam. I don't think cam lobes going flat had anything to do with a oil plug not squirting at a distributor drive gear.
