I have found that idle quality suffers with the bigger carb. But wide open power suffers with the smaller carb. The 650 vacuum secounday carb, when jetted and sprung right, will feel better from idle to WOT. But my on track numbers show that the 750 makes more power with 331 cubic inches. The 750 can be tuned to be "ok" for daily driver. I usually go smaller unless I am looking for maximum power. If that's your deal then use the performer rpm, or try to find an old "Torker" manifold and the 750 carb.
