Oh yeah, the 6.2 with the 6 speed gets down. I've heard good things about the 6.0/6 speed too. I've driven 6.0/4 speed and I'm not impressed.
Torque! Rocket power vs LS power

olds307 and 403 , maybe you should reread what you posted.
"I towed 6500 to 7000 pounds with our work 2011 6L 3/4 quad cab 4x4, anything below 4000 sucked. I pulled the rpms up to 3500 rpm, 70 km/hr to 100 km/hr took forever to get there. These LS trucks are all the same, they suck below 4000 rpm, towing or not."
That's a pretty bold statement. My guess is that your hot rod 350 Rocket would feel pretty gutless in a 6000# truck towing a 6-7000# trailer too. I'm not getting in on either camp because it's an apples and pears comparison. Just pointing out that your argument has some pretty notable absolutes. I'm not even going to take the bait on the predictable 4L60e tangent.

The 6L 4spd was clapped out with broken off manifold studs, pretty gutless. The 6L 6 speed is the best of the LS trucks, I drove. The two 2017 5.3 LT with a 8 speeds I drove would mop the floor with it. And the LT has steadily been behind the 5L Coyote motor in HP and TQ, even in trucks.
I had an Olds 350 8.5 to 1, 5A 307 heads, 204/214 cam, shorty headers with 2.25" dual exhaust in a truck, same POS 4L60E, 3.73 gears, a 1500 stall, 265/75R16 in my 94 Z71. It was way better than the 5.3 with the exact same drivetrain, idle to 4000 rpm with the stock 450 cfm TBI with 350 sbc swirl port tune. With the 454 TBI and a proper tune, it would out perform this 6L BELOW 4000 rpm. The LS perform very well above that, not my cup of tea, sorry that multiple examples aren't enough🤷♂️.
I never towed that much. Keep going, still weak below 4000 rpm trailer or not😉. Maybe they cut the power in half on Canadian models🤔.
Well, I guess I can't argue with that type of quantative data. It's official, all LS engines suck.
Can't imagine why anyone would buy gas trucks if towing any kind of weight is going to be a regular part of the program
One issue I see in the comparison is you have what appears to be 2 different dynos doing the testing which can make a big difference in the numbers
That Coyote is a ripper no doubt. I only rode shotgun, so I can't comment on the low end, but it lit the tires up in an F150 in FL and pulled like a banshee.
See sig, I tow in OD with boost. I don't like the cost of entry or the cost of maintenance of a diesel.
