OK, the old Autolite on my 72 Mach 1 is worn out. The linkage is so worn that it keeps slipping off. The question is what carb would be good for my car. It is a 72 Mach 1, 351C 4bbl, C-6 auto transmission. The engine is stock with the exception of being bored 30 over during it's only rebuild. I need a good carb for crusing, easy starting, and ha ha decent fuel mileage. What type and cfm would be decent for this car, and keeping in mind that I ned the kickdown lever for my trans. Thanks Rick

If you plan on using your spreadbore intake, you are kind of limited to the 4350 you have now. Do you plan on changing it?

Don't really want to. The car is very original, or has original accessories or options that were available in 72. Also it has functional Ram Air, so the original air cleaner has to be used. Also, I was just looking through the latest Summitt catalog. They have a 625 cfm carter for a Ford. I assume this has all the throttle cable adapters i need. Also for this carburetor they list a spreadbore adapter kit. Would this be a good choice for my stock engine?
Thanks Rick

Well then it looks like the 4350 is the carb for you. Either rebuilt that one or buy another like it.

You know, you could still use the ram air cleaner with a Holley mounted on a aluminum manifold and just put your current carb and intake in safe storage. You could even paint the aluminum intake and very few would notice the difference, especially if you grind the lettering off the intake.

Are you sure the Carter takes the 5 1/8" opening Ford air cleaner? I don't believe it does. The opening on a Carter is smaller, and I don't think they have a Ford sized carb.

Also, you don't want to use that mickey mouse adapter, trust me. If you don't want to swap intakes, just fix up another 4350.

and a simple inexpensive adapter/spacer would make for a very sweet street performance carb.

Steve, you say 4350, but in looking at the books and iding by carb by the pictures, I have a 4300, not a 4300D, just a 4300. I guess I am going to try and find another carb to rebuild, or donate the linkage that is worn out on mine. Anyone got a decent 4300 for a 72 Mach 351C with an automatic tranny?

Believe it or not, I sold one not too long ago for $225. Manual tranny carb, though.

Rick,

Have you thought about sending your old carb to Pony Carburetor and having it restored? They show a cost on the website of $259.50 for a standard or $349.50 for the plated version.
