The 770 and the 750 are basically the same carburetor. Same venturi size and booster. Just streamlined a little bit.
He could take either one of them carbs mentioned here and put a K&N stub stack on it and it will make great low end torque and high end horse power while enhancing booster signal. This whole paragraph only holds true to a vacuum sec. carb. The stubstack contours the air entering the carb much like milling the whole choke horn off. It will add about 5 hp by it self. I would only run any thing less than a 750 vac. sec. on a totally stock motor or a motor smaller than a 350cid such as 327 on down.


Just another opinion Ray
