Pro Charger intercooler with 3" inlet and 3 1/2" outlet for a 496 HO. Anybody have one for sale? Or maybe know of a good replacement other than the really expensive crappy stock piece.

I replaced my Pro Charger intercooler with one from http://www.frozenboost.com/. It is a nice and well built unit that I have not had any problems with. You may need to get creative when it comes to mounting one of them though. I also don't know if they make one as per your in/out specs...

Thanks for the link. I think I found one on there that will work.
