Yes the thrust brg is narrower, cast crank engine is easy to tell if the stampings are there on the deck by the alternator, there will be an "E" right after the "225".

I’ve heard that, but there also seems to be some disagreement on the truth behind that statement. Mines a 225R but another guy said his 225R has a cast crank. It’s a 77, and I was told all production of forged cranks for the slant was discontinued in the 76 model year?

for clarity’s sake, my whole casting number is 7225R - 1 212E
