I think one difference is that if this is your first newer model vehicle with Torque Management it takes a while to get use to. I remember I had a 1988 Chevy Silverado with a 350 and you could just stomp on it and it would roast the tires. If you got it in a corner it would spin till the 700R4 shifted at around 40 MPH. That was with a 3.42 Open Diff. One thing to keep in mind at that time it was rated 220 Horsepower but it was running 225-75-16 tires. When I traded for a 2000 Model Silverado that had 285 Horsepower, 3.73 Rear End LSD, 265-75-16 tires.I was diappointed because you would stomp it and it would just lag till you got moving. So you feel like with 65 more horsepower you should see a improvement.I can see where you are coming from. In the defense of that truck it was an extended cab with alot more features than my old Chevy truck had. Also older vehicles years ago you did not have to Power Brake to get them to spin. You simply came off the brake and mashed to the floor and the wheels would start spinning and smoking. Some Peoples truck here may do that my 2012 Hemi truck with a 3.92 wont. I dont know that it is necessarily bad,(tire costs,unintentional spinning by wife) JUST DIFFERENT The 454 is moster and you have one of the last years that had some of the benefits of modern technology with Vortec.
