Was wondering which carb would be better. Holley 670 or 770 and would 4bbl be better than a 2bbl ? Its going on AMC 360 v8 5.9 L .

this question is a fairly broad question that you need to drill down further to get the best answer. I will add to the above what intake?
I think that if you are looking for good reliable carburetor stick with the Motorcarft 2bbl that came on the 360 would be best all around carb for a Jeep. If you want some more performance swapping to an Edelbrock intake with a 2bbl adapter and a large bore Motorcraft 2bbl from a motor like a 390 would be pretty good
if you have a mild/stock engine the 670. If you are going for more performance and have the intake/cam/exhaust to back it up the 770 would be the one to get.
Holleys have an issue with the fuel vent location in the float bowl and have a plastic tube that you can buy to keep the fuel from rushing up and out the float bowl when you are going up an incline
I currently have a Holley 650 4160 with side hung floats and have converted the secondary's to the 4150 style removable jets
cant wait to get it on the road with it
