1956 single four barrel carb usage

[Edward M.]

I just ran across something very interesting. This is apparently from the "Straight Axle Corvette Technical Guide - Mechanical"

1-Carb Part No Carter Model Notes
1955-56 3724158 2351S WCFB 1955 after about VIN -1483, 1956 until AIM 5-28-56

1956-57 3733246 2366SA WCFB from AIM 5-28-56 to AIM 1-7-57

This would indicate (at least according to them) that the correct carb for an early 1956 single four car (at least up to 5-28-56) would be a 2351S. After that a 1956 single four car would have a 2366SA carb.

Does that make sense?

My Carter reference indicates that 1956 single four WCFBs (without regard to pass car or Corvette) would be either 2366S or 2366SA. And what exactly is the diffference between a 2366S and a 2366SA?

my listing show no difference in internal parts or specs between 2366-S and a 2366-SA

Often times Carter would make a small change in say the air bleeds (as opposed to an obvious jet/rod change) which was significant enough to warrant a Model designation change.

Ed, here's preview of the revised 56-7 JM carb chart Gary Hodges and others NCRS members contributed to. Foot notes explain some of the differences. Let me know if you need the Carter sheets on these carbs. Gary....

Thanks Gary. I am looking at the 56 1x4 carb info and it makes a lot of sense to me.

Now, the 64 thousand dollar question. When did the change from 2366S to 2366SA occur? Do we have any idea?

Great info, thanks again!
