Either way the engine trans combo is awesome and you will be very happy with either one I would say.I have put a 6.0 4l80e in my 68 LeMans convert and a 5.3 4l60E in my 89 C1500 loved them both. Also, depending on who reflashes your PCM for your truck, it will open up some HP and torque just by changing a few maps inside.

So maybe he doesn't know what he has and it's a 6.0?
