Hey guys! I've just got my TPI up and running, and I'm already looking into a newer engine, LOL I've got my grubby mitts on an NV4500 / pass drop NP241, and will be putting them behind the TPI 350 for now, but in the future I'd like to swap in either an 8.1L or a 6.0L My truck will not be a daily driver, and will primiarly be used for Sunday morning cruising, or driving to the lake and back with either a few quads behind it, or the boat. I will regularly be using it to haul a 1000 gallon water tank on a trailer as well. I know not a lot of guys have swapped them around yet, but if you were to swap, which would you go for? I kinda want the 8.1L, for the extra torque, and for the ability to brag that I have a 496 in my truck However, I've read that they occasionally suffer from excessive oil consumption, piston slapping, and that they all are drive by wire units (I hate the drive by wire pedals, way too soft) The 6.0L would require me to fab up some engine mounts (appears pretty simple), but its possible to get them with cabled throttle bodies, and they are far more common. Either way I'd aim to find a totalled truck so I can get everything off it, and pull it myself so I don't have anyone to blame with regards to cut wires but myself. I'd pull everything from the exhaust to every last little hose. What would you guys go for? Anyone here perform either swap and have any tips or advice?
