Carb too big?

It depends on what you are familiar with and can work on.

If you want to just bolt it on out of the box and go, then I would go Edelbrock.

If you are familiar with Holleys and tuning them in, then I would go Holley...

That's it in a nutshell. Depends what your comfortable with. Both will work with great success.

I run an Eddie 500.:burnout:
