I agree though, the 6.0 seems to be a much better platform overall

I figure alot of people go to a 427 or larger out of the LSX block. Keep in mind not building for any one reason other then because I thnk it woudl be cool.Not sure how long if it will work out, and if it doesn't then it doesn't no big deal. I think the 6.0is a great step up I have one of those laying around as well. But the 8.1L is more wow then a 6.0L I think.
Already talked to my engine builder, with some good pistons, cam, and a port job on the heads, he thinks the engine will be a freakn beast.
But thats months away for today.

Doesnt the 8.1l use big block chevy parts and not lsx as far as aftermarket goes?
yeah its like a 7th gen big block i think and its nothing like an LSx and apparently different form the 5th and 6th gen big block as far as block construction but i feel sure internals are the same.

I helped (just a little welding) a customer with his twin turbo rear mount on his 8.1L 3/4 ton. He's running 10psi, pump and larger injectors. The allison takes quite a bit of the power, but
It's pretty fast and lots of torque, but i think a 6L would stay with it.
Sounds like a neat project!
good luck
