Better Performance Output

Raul said

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.

67200 is the Proform number. I personally wouldn't use a 4779 Holley as they came with a fairly rich tune up and the last I knew they don't have replaceable airbleeds etc.

A few days ago a guy had a Proform 750 for sale here in the FABO for sale section with a pretty righteous price.

FWIW I also don't run carbs with a choke. Other than a fast idle the choke is just a pain in the ***.
