Carb recommendations for my 340

A edelbrock performer rpm and a thermoquad carburetor and your good to go. Is this bad choice?
performer rpm is a square bore, which means you'd have to run a spacer/adapter. also no choke well. so if you wanted to run a TQ you'd need to find a superquad, electric choke conversion parts if those exist, or rig up a manual choke.

aftermarket dual plane spread bore options are: performer, weiand 8007, or offy 5685.


if you like tuning carbs, TQ's are great. if you want to put something on and not have to fuss with it there's better options. options that involve not hunting down parts and paying thru the nose for them.
