Just trying to get something straight that I think someone else in another forum is in error.
I know about the M-20, M-21 & M-22 identification rings on input shaft and approximately when the M-22 started but this guy claims there was a WIDE RATIO M-22!! ![]() News to me. Any of you heard or better yet know of one? ![]() Pontiac did not use them until '70 and they were mandatory in '71/'72 with the 455HO and I know Buick and Olds used them but not sure of application. Any help would be appreciated.
