JWL has quite a bit of carb information at different configurations on the dyno. He showed modest gains with two 94 on a basically stock engine. With some engine modification the 3x2 will outperform a 2x2 at higher rpms, but the 4bl gives the best numbers. I'm not a 4bl fan on a flathead, so looks wins out!
