That's the difference between a Quadrajet and a Holley. If you go with the Holley, like B said, you better know somebody that knows how to work on it. If you go with a Qjet, once you put it on(unless you change your motor fundamentally), you don't ever have to touch it again.
no, I didnt say that...I said , that NO MATTER WHICH you use, it should be best to use the one that YOU or Someone You Know is knowledgeable to work on....If you know Carter , buy it, if you dont work on it but your buddy does and he likes Q jet ,buy a Q jet...but as Mike said...since he has a Holley, why not fix it? Unless its too far gone to fix?? parts easy to come buy ,its an easy one to work on...
