The cam oiling issues started with the 215/223 and continued into the y-block era...when you rebuild them a tiny groove cut into the cam solves that issue...
312 with the larger main bore and same size maincaps wasn´t one of fords brightest idees...312 crank turned down to the smaller mainbearing size and put into a 292 block works better. Or new steel maincaps.
