5.3 Truck Manifold VS. LS1 Manifold -- PROS? CONS?
Sorry for the long title. So I'm picking up a 2001 5.3 out of a Silverado Friday, along with the 4L60E Trans, and all of the associated wiring, etc.
A friend of mine recently finished with a swap, with basically the same setup (hence the inspiration for mine) but seeing that he had some minor clearance issues with the fitment of his intake manifold with the hood, I'm STRONGLY considering one of the LS1/LS6 intake manifolds.
So what would be the pros/cons of the truck intake vs. the LS1/LS6 variation of intake manifolds? Fitment, Performance, MPG issues, anything that you can think of?
