just drop a 5.9L cummins in there. . .
12 valve 5.9L/5spd manual. . .
24 valve 5.9L/6spd manual. . .
With today's gas prices running a gas engine in anything heavyer than a 3/4 ton is a waste of money. . .
with the cummins diesel in that truck you would get 12-16 mpg easy loaded maybe 17-19 empty. . . the 292 might get 9mpg empty at best an 5mpg loaded and it ain't going to have any power in the hill's with a load. . .
I'm a die hard but even i'm updateing. .
