Don't tempt me, I want to keep it a diesel but a complete 8.1L with the full harness out of an 02 3500HD is for sale about an hour and a half away.
I want a Duramax in this truck but having a 454 and a 496 is extremely appealing.
It is Friday night. I bet the people with the 8.1 will be up for another 1.5 hrs.
