myfirstcarwasa73trk do the six....i can pull a trailer with mine and have no problems i also get about 22mpg 275 70 15 in the rear with a 373 set up lots of good torque. but i have to admit i just converted i am a die hard 350 and 4.3 chevy guy i almost put a 4.3 with a 5spd in my truck for the gas mileage and familiarity with the engine. I am happy so far with the l6 and the next truck i am building is gonna have a 4bt cummins so i am just as confused.
