My 401 came with the motorcraft 4350 carb, and when I swapped motors it went on my 360. It did allright on hills, but as soon as the heep would bounce it would cut out on me.
So I went with a quadrajet on my 360. The install wasn't bad but there are a few things to think about. The spreadbore/square bore adapter from partsource is about $20 but if you have the spreadbore amc intake it will take a bit of machining to make the quadrajet fit. The linkage might also need a bit of tweeking to make work.
Now I can stop and go in the middle of hillclimbs which previously used to take me full throttle assaults to make over. I would never run a carter afb or edelbrock carb off road, they're strictly street carbs as far as I'm concerned.
Propane is great off road, but your range would be reduced. FI would be the hot ticket, but the $1500 (rough guess) price tag's a bit scary. So the holley truck avenger, or the quadrajet are the only logical solutions IMO.
