any thoughts on the intake situation? I read all over the place that the truck intake is a great performer (though ugly) up until 5500rpm, then it falls flat. I'll barely every be in that rpm range. I want low-mid range torque. More than anything I don't want to admit defeat and return a bunch of return style fuel fittings and stuff. lol
I would agree that the truck intake performs fine. The car intakes definitely look better, but you have to factor into the cost of things like relocating accessories to clear the throttle body. If you really want a car intake and you want to keep the return fuel rail, a '97 or '98 'vette fuel rail is return style and it bolts right on all the ls1 and ls6 intakes.

Here's a link to an article comparing several OE manifolds and an aftermarket FAST one: http://www.powerperformancenews.com/...fast-ls-intake Scroll almost to the bottom of the linked article and there's a graph of all the intake results.
