It sounds like you want to use the factory carb, and you don't really want to fiddle with a new intake that might alter some attaching hardware.

Why exactly are you wanting to change?

Mopar made an aluminum version of the factory intake. I will cost about what a CH4B will cost, $150.

I am skeptical of the Performer naysayers. I have one and I think it looks pretty good, but have not run it, so it could very well be a turd, I don't know.
