This question continues to get asked a lot so I thought I'd put these pics from my files, for reference. Works in most cases, but not all.

my salvage motor doesn't have the dot, lots of confusing changes, only the merc valve covers and the 57 up intake & dizzy makes me think it might be a 312, guess the pan comes off next, Gary
