Carb help

[98SVT - was 06GT]

I have a Holley C50F-9510-M (list 3530 date 593 4-3-65)carb. Some sites list it a 289 HiPo - but others say no Holleys on Mustangs (except GT350) until 1967.
What is it??? Any idea on value - complete used?

It's the factory carburetor for 1966 Comet / Fairlane GT390. If it's complete and rebuildable maybe a $200 - $300 core.

No Holleys on Mustangs until the GT390 came along. Shelbys are different of course.

Should be C6OF
Great carbs. The 67-68 ones get kinda weird and specific, the C6s are good and have a very "normal" setup.

I realize this is an old topic but when I purchased my '66 Hertz back in 2004 it came with one of these Holley carbs (C60F version 3530).  I believe they originally came with an automatic choke but this one has a manual choke linkage.  Choke cable was not hooked up probably because the butterfly is missing!  Carb works fine after some initial warmup.  A carb swap for a more correct Autolite is coming up.  Just got the brakes finished.
