What kind of performance are you looking for in a 3/4 or 1 ton truck? It's 310 hp and 450 ft llbs torque stock. Get it breathing better with a cai and headers, and you have added another 20 hp, and 35 ft lbs of torque. The V10 Magnum will out perform any gasoline engine on the market when you understand what kind of performance it was designed to deliver. No, you will not go 0 to 60 in 5 seconds, nope, you will not get 20 mpg. Yes, you will ****** that Ford, Chevy or riceburner out of the mud without breathing hard. Yes, you will tow that 10,000 lb 5th wheel up that mountain easy as kiss my hand. It does what it does very well, but don't try to make it a hot rod.
