Hello,
I just registered and am enjoying all the info on this forum. I have a 67 Camaro with a 327 that is all stock as far as I know. I just ordered your book on Quadrajets and look forward to reading it and rebuilding my carb. After looking at the carb, it is mfg. by Carter and the number on it is 4447S with G1 under that number.
Any chance this is the original carb and is it the same quality as the carb's built by quadrajet? Cliff can you also tell me what parts I need to order to do a complete rebuild on this carb.
Thanks!

Welcome to CHP!
4447S was used on the '67 327cid Chevrolet engine. The G1 is the date code, which indicates July, 1971. So, this is probably a Service Replacement carb.

Thanks for the welcome and reply Ethan1.

Can someone tell me what this carter number would be close to in the Rochester built carbs?

I believe the 4447S is a 4MV carburetor. Are you trying to find the correct carb for your application? What is the HP rating on the 327cid? I believe some of the '67 327s came with a 2-bbl. Could be wrong though.

It is the 275 hp 327 with a 4bbl carb. I guess what I'm trying to figure out is what Rochester model corresponds with the carter model that I have. Maybe I'm confused (which ain't hard) and there's not one that matches. The reason I would like to know if there is one is because in Cliffs book he refers to the carbs a lot by the Rochester model number. Hope this makes some since and thanks for helping me out.

I don't know. The 4447S is a 4MV Rochester carb. Maybe Cliff will know.

See if this site helps out.

Carter built a lot of carburetors for GM as Rochester was not able to keep up with production. All of the original units will be numbered the same as Rochester carbs, but they will have a different method to date them.
I would also add here than original 1967 and many 1968 units used a round tag in lieu of stamping the castings.
If you have a 67 carburetor that is stamped, either Rochester or Carter built, it's going to be an SR carb.
Rochester units use Julian dates, Carter's used a letter/number. A 1967 Rochester carb might be dated 0017, indicating January 01, 1967, where a Carter would be A7, or January 1967.
Rochester Service Replacement carburetors still used the original numbers, at least until 1975, but they will be missing the Plant Code.
Carter SR carburetors used four numbers followed by an "S".
Most Rochester SR carbs post 1974 will use 170549XX numbers. For example, the SR carburetors for the 73-74 Pontiac Super Duty engines were numbered 17054910 or 17054911.
Hope this helps some?.....Cliff
