Re: 455 HO Engine WC Code 4Spd

Actually, that is not correct. Ram-Air and non-Ram-Air used the same block codes. In 71 there were 3 455HO block codes, WC (455HO with M22), WL (455HO with 3-speed manual (yes there were a few built)), and YE (455HO with Th400). In 72 they had 4 455HO block codes, an auto and manual trans version for each "with" and "without" unitized distributor.
