[QUOTE="64FJ40, post: 824727, member: 16057"] I've still got the stock 64 "Early" F. Since I still have the original intake manifold, the best carb for it, by far, was the stock one-barrel. Mine finally got too worn to rebuild anymore since the vacuum leak around the throttle shaft was not easily remedied. When it worked well, it ran fine at just about any angle that kept the tires on the ground. I ended up converting to a Weber 32/36. It actually runs pretty well, but I'm still not sure it's working to it's potential due to the crappy throttle linkage that I haven't gotten around to fixing (don't ever buy anything from JTOutfitters). The throttle response is smoother than the stock one, but it doesn't handle sidehills very well in comparison. If you still have the stock cylinder head on your 66 motor, you're really limited in what you can fit. The stock intake manifold is set up for a 1bbl, and adapter plates to anything other than a Weber 2bbl (either a 32/36 or a 38/38) are virtually nonexistant unless you make your own. It sounds like you have an aftermarket intake manifold, so the bolt pattern may be a little more universal which would open up more options. All that said, you don't need a very big carb. It's basically a 3.9L tractor motor and with a header realistically redlines at about 4K rpm or so? I RARELY get mine over 3K. I don't know how many CFM that is, but it's not anywhere close to what most of those carbs designed for SBCs. [/QUOTE]
