Vortech 15psi, 2V 4.6, cams, pulls to 6,200 RPM right now, ~ 525 whp There is an aftermarket TB/plenum on the stock PI intake Would it be worth switching over to the Trick Flow Street Burner, Bullitt, or other intake (what else is even out there)? Let me re-phrase that a little bit, at what price would it be worth it? Find a used intake for $400, make another 25hp...that would make it worth it to me I guess. Really looking for before/after experience from someone who's actually done it. I don't trust the old magazine reviews, and all I hear is "you should/would/could gain xx hp"
