ok guys, trying to determine what cfm my 4bl carter cvs is? it is on my "new" 61 lancer (offy manifold). is there a way to identify cfm via numbers on the carb? my best guess is 500cfm.........................steve

How about a picture or a Stock number from the bottom tab or corner of the carb.

Carter 4934S is an AVS rather than an AFB and is for a 1970 340 with an automatic transmission, without EEC or Air Conditioning. I'd say it's about 600-650 CFM.

thnx josh..................oooof, thats way too much carb i think,huh???? wonder if i should start looking for a 390 holley........steve

The AVS should be able to work just fine with the vaccuum secondaries, but I'd bet you'd get better signal and metering from the 390 (if you're trying to strike a bargain between 'power' and 'mileage'...

-D.Idiot

D.I. , wouldnt i need an adapter plate for the holley, plus, i have the original bell crank gas pedal setup. i assume i would need the newer style gas pedal along w/lokar kickdown cable??? or has anyone adapted the 390 to the bell crank like my carter ??????????????????

Carter AVS and Holley used the same bolt pattern. It's the AFB that's a bit smaller. All three use the same the Offy adapter plate.
A newer cable throttle with Lokar or Bouchillon cable KD would be way less work that adapting the rod throttle and bell crank KD.
Another KD option with a newer cable throttle, use OEM 1bbl KD linkage the Offy KD linkage adapter.

thnx cecil, i think ill just stick w/the carter, although the accelerator pump is shot. im hoping to find a rebuild kit for it(avs). if not, ill buy an edlebrock 500 cfm performer, as it is a direct bolt in replacement(throttle linkage,etc)....I HOPE !! .......................ss
