Hey guys iv got a holley 750 dual feed carb id like to sell its not a double pumper, i i just rebuilt it, everything inside is new but the float bowls. It has a quick change spring kit for the secondaries so you can control when they open(it has vaccume secondaries) i have all the springs to go with it, it has size 68 jets in it and a 6.0 power valve, i had it on my camaro for about a week and i didnt like it, im in the process of going to the stealth ram now
