Again, 320/390 isn't going to be shit with a 4spd/OD towing a 6k boat.
Shake away brother.
To give you an idea. We have a 2015 crew cab 4 wheel drive Silverado 5.3 rated at 355/383. Tow rating 11200 in stock configuration. I leveled the truck, added 33 E rated BFG all terrains, and 5100 Bilsteins.
Stock tow rating factors p rated tires. We picked up or 335 Hallett in Havasu and pulled it to Mead cruising 55-60 easily. The truck would easily get out more if I let it.
Trans temp never creeped over 180 and coolant hit 212 for a few min. Pulling from the lake to Storage is a huge hill. 4k it pulls the hill at dead on 50mph. Does not get over 215 in 110 ambient temp.
I am giving you actual real world numbers and experience. Not some armchair QB BS that a New car salesmen would at the dealer telling you this truck will pull the spaceshuttle up kilamanjaro.
