I found 5 Carter Afb Carbs. I did the research and found what year/engine they were on. I need help on the cfm ratings. Any help would be appreciated. Thank you, Matt


Heres the list:

1959 Carter #2814S Caddy 390ci
1960 Carter #2951S Caddy 390ci (I found 2 of these)
1964 Carter #3656S Caddy 429ci
1965 Carter #3903S Caddy 429ci

I am looking for the cfm ratings.

 

With some measuring, you can determine what CFM they should be...

CFM Venturi Diameter Bore Diameter
primary secondary primary secondary
--------------------------------------------------------
400 1 1/8 1 1/4 1 7/16 1 7/16
500 1 3/16 1 1/4 1 7/16 1 11/16
575 1 1/4 1 9/16 1 9/16 1 11/16
625 1 3/16 1 9/16 1 7/16 1 11/16
750 1 7/16 1 9/16 1 11/16 1 11/16


For some reason, I cannot get my chart to line up properly, no matter HOW I do it....
