Better Performance Output

Ok, I decided to try a Holly 750 Double Pumper but noticed there are many models to choose from, which model would perform best? Would the aluminum holly be a good performance gain? I would definitely need one with an electric choke. And I would be opting to tune the carburetor while it is on a dyno.
This I somewhat answered in the private message you sent me. I’m not going to repeat it here. You could always do yourself a genuine favor, and call quick fuel. (AKA Holley.)
