Re: 637 v8
hi guys. The correct designation for the carb on the 637 is a "WWC", not a "WW". This same carb design was on all 401 & 478 engines. It also came on the 351E and M engines (M engine is oil pr. governed). The "WW" was a small cfm carb used by various GM divisions and Mopar divisions. I hope this is of some assistance in this discussion.
Cordially,
