239 flathead. Offy wcfb square 4 pattern. Right now a list 1273 quad Holley that is way too big and operating very poorly. Car is around town car without any race applications. Mild cam. I want to use a 4-to-2 adapter and use a 2 barrel Rochester/Carter. If electric choke, has to fit between the tubes on the center-positioned heads. You people know everything: I was short-changed on carburetor knowledge, thinking God said, Schmarburetor, and took a pass. What to use?
