I was at the dealer the other day.
Wanted to order a 6.2L in a RCSB. They were surprised I asked and they told nope won't happen.
So I asked if I bought a 6.2l could they swap it and honor the warranty.
Nope not happening.
GM does not care about performance in trucks. They might make a better pull rig. Butbthe hot rod truck died a long time ago.
Side note. We can turbos to any of the trucks.
