I have the chrome edelbrock on mine. It's no whiplashing gain of hp but it's noticeable and i am very happy with it.
Just make sure you stay away from borla crap, i had the borla installed at first but it was burning my plug wires (the cylinder closest to the firewall on the driver's side). The shop where i got it from and myself left like 6 messages for borla tech support/customer service but never got a call back!
I tried header wrap and foil up the wires but it was still burning them. I thought of using shorter plug wire or mickey mouse some bracket but then again, why should i go thru all the hassle when in fact borla is the one who design a poor product in the first place? So I ended up taking the borla out and replaced them with the edelbrock and have been happily ever since
Oh, one more thing, the borla doesn't even come with flange gaskets. And nobody (not even dealers) had them in stock at the time so i had to make my own
And yes, edelbrock came with them.
