1972 Mach 1 Q code with Factory ram air
Hi all,
My 4300-D spread bore is getting too beat up to keep running. I am looking for suggestions on which would
be the best replacement carb for it. My car is an automatic.

thanks

Can't really go wrong with any brand name carb, holley, edelbroken, quickfuel, etc. Although I have heard Holley QC is downhill but I haven't bought a brand new carb in a bit... Just make sure you tune it there is no such thing as ready to run out of the box. Also make sure you get a square bore carb, or verify you have room to run a adapter plate to match intake. Just out of curiosity, what makes you say the 4300d is too beat up?
