Over heating, poor performance are just a few of things that happen when you don't do your homework. I learn by doing, and I learn everything the hard way. That said, the only difference between the car engine and truck engine are the lifters. I kinda like the idea of quiet running engine. Being a 3/4 ton may limit your options for better rear axle ratio, but 4:10s won't get you up to freeway speeds, for long distance. The cooling can be fixed with the water pump modification, and or radiator. Oh yeah, what about the brakes, and steering, are they up to par? I do know a 350 isn't the always the answer! Been there done that.
