Reminds me of a sticker on the top of a crapper(not sure if it was a true crapper brand....but) the other day. It said, "If you have a short bat, step closer to the plate"
So with that, Yes a rig with more hp and the same torque with proper gearing will tow faster than the same rig with a less HP, same torque motor. The how much is another story. My 96 K3500 with a 185/385 diesel with 5 gears, generally speaking was a bit slower, but at times did better than the 235/385 tbi 454 in my 88 K3500 with a 3 sp auto. The kicker was if I could keep which in its power band. The 96 with 5 gears for the most part did better, as it was better setup gear wise. BUT, if on a 3-4% grade in the gear below direct for both, which was about equal in reduction for both, the 454 would out pull the diesel by a few MPH, talking maybe 5mph at 15K lbs.
So with that....... take this to the top sticky.
