The two Carter-Weber carbs (32 DFT or 32/32, I guess) were the ones I used.

They were great for starting, and very nice for cruising; but, they lacked high-end "power".
I also think they looked quite nice.

A single carb was used on 1600cc Ford Pinto engines - 97 cubic inches

I switched to a single two-barrel Holley AA-1 carburetor (from a GMC 302) with adjustable main jets (my 261 is bored 0.060 resulting in around 270 ci).

It performs much better. It can be tuned to provide high-end "pull-power" that does not taper-off during "acceleration tests".

This is with Fenton dual headers and original 1960 261 "modified lift" cam.
