holley or edelbrock?

Ethier will do. The Carter is a little more confusing to tune since your doing math alot between the rod and jet and then the step up size in power mode. But I do like them alot. Super fine tuning can be a pain for ethier carb when your new to it all.

A Holley is alittle easier to tune because your just doing jets. Once you figure out the power valve size needed, as in vacuum on the engine divided by 2 equals power valve size, your done there. Then it's just larger or smaller jets to swap in.

The Holley can be a little messy when you pull the bowls off. Just get a cup to catch the gas inside the bowl. Holley also sells bowls with screws on the back to quickly change the jets without bowl removal. A little expensive, but worht it if you race or tune alot for varied conditions.

The Carter has the top half come off, but is a pain with the little clips. Other than that, it is easy.
They both come with instructions on how to help tune and theres plenty of info on the web. A O2 meter would be great to add on.
