PACCAR MX13 EPA10 equipped with a 18speed in a 386 peterbilt. At 455hp and 580k miles will it live hauling asphalt grossing 160k after? Possible to swap motor to a CAT down the road?
It will survive, it will just be painfully slow. I have a 475hp pulling 130k sometimes and she's a toad. And, from my understanding - legally - you're not allowed to put an engine in a truck if it didn't come from factory with that engine.
Not to mention the hassle of wiring and computer. And everything else needed to make it work with everything.
