As the title implies, does anyone know of any company that makes aftermarket intake manifolds for the 5.3? Or maybe of something off of another application (Trans Am, Camaro?) that can be made to fit on the 5.3?

It's not even worth the swap. Your truck one flows just fine and is great for torque. Hell I've seen a few guys that showed losses at the track with the LS6 manifold.

Thanks for the info man. I guess I'll leave well enough alone. lol

Money is better spent elsewhere.

Dont even bother. Leave the tall truck intake on there.

you dont need to change the manifold unlees you went with a slightly big cam

I'd say more like a set of heavy breathing cnc heads and a big cam... but even then... might as well start looking at a 6.0 or something.
