LSXR and LSXRT Top Shells
LSXR and LSXRT Top Shells First off, I've already contacted FAST with this question a few days ago and haven't gotten a response yet. I Google searched as well and still found nothing, so I'm hoping someone on here might know.
My question is whether or not the top shells are interchangeable between the shorter LSXR car intake and the tall *** LSXRT truck intake. I originally intended to use it in my Mustang where hood clearance wasn't a concern, but I'm switching gears and wanting to use it in one of my Fbodies.

Verdad Gallardo It seems as though you were wrong. The top shells were swapped out in a recent dyno test.
"For this test, we replaced the standard LSXR upper intake section with the larger LSXRT intake. Often referred to as the truck intake, the LSXRT top simply offers increased plenum volume on this adjustable intake application. This combination was still equipped with the short runners used in the previous test. "

Is this based on personal experience or are you going off the picture? Considering the difference in height of the two shells, the distance and angle from the lens will be different and skew the shape a little bit. I don't think they're that different that they wont interchange.

Look at the curvature of the gasket surface on the lower right corner of each piece as it us in the pic. The curves are different. One has a fairly sharp corner, and the other has that corner "smoothed out" quite a bit. If that is due to the photo angle then I stand corrected. I was only going off the pic.

It is exactly what KCS said, difference of height of the 2 shells makes it look different
in the picture, they are EXACTLY the same, I personally bolted both of them on the
2 different bases, and one is a LS7 base and the other is a Cathedral base.
Camara angle as well.
