Correct carburetor for '67 289 2V?
« on: May 03, 2015, 05:33:57 PM »
I'm trying to track down the correct economizer for the 2100 carburetor on my '67 289.  The carburetor currently on the car isn't the original, and the original tag has been replaced by a generic tag from a rebuilder service.  Also, it looks like the body of the carb has been blasted or something, and some of the stamped numbers are missing.

So far, I've been looking in Bob Mannel's book, and I've come up with two possibilities for a carburetor:
--C7DF-F, 2100 2V, with 1.04 venturis, without Thermactor, for automatic transmission
--C7DR-R, 2100 2V, with 1.14 venturis, without Thermactor, for automatic transmission.

Which of these is correct? This is a '67 289, 2V, without Thermactor, with C4 automatic.

Also, should the heater hose have originally routed alongside the carburetor to warm the choke?  It's not set up that way now, but again, this isn't the original carburetor to the car.

Without knowing your definition of 'economizer', I would surmise that it is the one with 1.02" venturi?

My Pony Carburetor book states that the venturi sizes for Autolite 2100's in 1967, was 1.02" or 1.14" for the Mustang.

It's even more confusing in Ford Car Parts, same applications but with different economizers. There are clues. Without getting into a long discussion, C7DF-R should be the correct carb. The economizer is based on the venturi size and you need to determine what carburetor size you have first.
The heater hose should be routed along side the choke the same way as 65 and 66 2V carbs with the shield/hose retainer.

I should've said power valve.  I've heard it called both things.  Thanks!
