    1997 K1500 ecsb, 5.0L 4L60E F44, 3.73, 245/75/16 tires.

    A few years ago towed a bumper pull trailer + load at 8800 pounds towed. Absolutely no problems with 'heat loading'. Trans temperature hovered around the 190~200F mark, towing in 3rd, right at the torque peak of the 5.0L.

    Factory oil to water cooler in the rad, no additional cooler.

    I wouldn't recommend this on a daily basis, but it will do that.

    Go with the big block. I've had the small block tbi and vortec and 6.5 diesel, I now have a 454 vortec and it puts all the above mentioned to shame. I also have a 5 speed, so much better for towing

    @Jorge6.5 wasnt your 6.5L an auto though? :) 5 speed puts anything to shame, I would much rather drive a 350 5spd than a 454 auto.

    Much rather drive 6.5L 5spd than any of them. ;)

    Yes the 6.5 was auto. Had it been 5 speed, I would still have that truck today
