This is to weird. I was just thinking about getting a bigger carb. for my Mustang. I have a custom worked Holley 650 double pumper with most of the upgraded goodies. It probably flows very close to a 750. It has killer throttle response. A normal 650 double pumper should easily be enough for a stock 351 or even a mildly modified one so my carb would easily do the job. Let me know if he would be interested and I will try to come up with a price for ya.
