I know two people with "built" 302s and Fenton headers and the original intake with AA-1 carb with adjustable jets.
One will soon have his rebuilt 302 run on a dynomometer (to determine hp and to tune the carburetor). He has special pistons that result in higher compression than stock.
I am using a GMC 302's AA-1 carb on my 261 (bored to about 270) and is is very nice and it is easy to adjust/tune the add-on adjustable jets.
If you will not be using the AA-1, consider selling it in the Stovebolt.com Swap Meet (with its air cleaner).
