[Cobra #42]

I second Fixit opinion, I run Holley on all my cars with same type of engines. You need to get to a good shop that has a dyno that will check your fuel air ratio. Run in the area of 13 to 1 and you will love your carb. Buy some books and read about Holley's they are very adjustable, and easy to understand. But.... if you still want to junk your Holley carb, I'll pay shipping plus some beer money.
