[rfsmith48]

Folks,

Does anyone have a list of the crankshaft casting numbers for the different years of the 300 V8?

Thanks,

Rog, from 1984' TRW cat. X3007.  Forging #'s list make and stroke(possible V6/V8)? bu: 1357899,1378351,1378354 and bu/po: 1357898(V6).? Of course, these are all "Arma Steel"-cast cranks. Later Rover cranks are reportedly, "uprated material". I haven't heard of anyone breaking late Rover cranks.Good Luck, roverman.
