I beleive your right BambiKiller240 . My sbc has the same type of set up. I removed mine and tapped the hole and inserted a plug. This forces oil thru the filter period. And 90% of car crafter that do this mod, keep up on there oil and filter changes. But be warned ....... don't rev the motor cold, it could split the oil filter case. But we don't do that .... right
I know ADVANCE AUTO sells them right off the floor, but drunkenmaster is correct. As long as they fit the requirements they don't have to be "auto relays".
drunkenmaster, nice link.
