So I got around to disassembling the '63 427 short block I found. This engine looks to have not ever been apart. The crankshaft is grooved on all 5 main journals and the bearings are standard and say FoMoCo on them. Thing is the bearings are fully grooved too. Is that how Ford built these back in 1963 or are they later bearings? Guess there was a lot of concern about getting oil to the rod bearings!
