7-11 for a super sized slurpy, a coffee or what ever. So everybody can listen to your diesel idle. For those who don't have a credit in basic high school physics. Torque alone does not do work. Rpm does not perform work. Time does not perform work. It takes torque and rpm together to perform work. It's a calculation of torque and rpm with relation to time to raise a load against gravity and assorted frictional losses "per hour" . To determine which engine can either haul a larger weight uphill in the same period of time. Or raise the same weight in a shorter period of time. If lower rpm was better. Why did Ag manufactures change from a 540rpm pto to a 1000rpm pto to handle higher HP instead of a 250rpm pto? How it a race to haul live stock like a Nascar event uphill faster? As long as the vehicle keeps up with traffic in the right lane, it doesn't matter. How do you need 400HP to haul typical under 10,000lb load and rarely do any real world pickups haul 26,000lbs. A short time ago a 318 used to be considered just fine to haul 40 ton of freight plus the truck across country over two mountain ranges. What era of diesel engine "power" are you comparing to gasoline "power"? Reliability? Reliability or a modern epa diesel? Who are you kidding? It's been a long time since the glory days of the simple reliable 6BT and mechanical pump ISB Cummins diesel trucks. Ever have anything to do with any diesel with common rail high pressure injectors? Ever have anything to do with particulate filters, glow plugs, cooled egr, urea injection, cat converters, variable turbo's, two alternators, two batteries and more expensive filters. I haven't seen a gasser wax up a fuel filter either. Last time I checked gasoline runs 20% or so cheaper than diesel. It's been a while since the mid 2000's diesel price advantage at the pumps. I suppose if you have the money to spend on the luxury of a diesel in 2014. The glory days of diesel pickups and low diesel fuel prices from 1989 to at most 2006 is past. I see the old chev port injected 6.0 with a Crew cab, standard box with single rear wheels:4x4 w/ 6.0L (4.10 axle): 5,897 / 13,000 or....... 4x4 w/ 6.6L (3.73 axle): 5,897 / 13,000. Both 13,000lbs. Crew cab, long box with dual rear wheels:4x4 w/ 6.0L (4.10 axle): 5,987 / 13,200 or........ 4x4 w/ 6.6L (3.73 axle): 10,206 / 22,500 Really just how many pickups out there have the paperwork and driver with a class A to haul a trailer over 10,000lbs ? As for max weight in the pickup box, the gasser wins. Crew cab, long box (2WD) with dual rear wheels: 6.6L: 5,908 / 13,025 gross, 6.0L: 2,833 / 6,245 payload. 6.6L: 5,908 / 13,025 gross, 6.6L: 2,488 / 5,484 payload. As for power, the old outdated port injected gasser still makes more power until any recent diesel.On cheaper fuel. Horsepower (hp @ rpm): 322 @ 4,400rpm Torque (lb-ft @ rpm): 380 @ 4,200rpm Recommended fuel: Regular unleaded or E85 Ratings for the last simple and reliable Cummins. For the 2001–2002 model years, a standard output and high output ISB Cummins engine was offered. The standard outputwas rated to 235 horsepower (175 kW; 238 PS) and 460 pound-feet (624 N·m) when equipped with either a manual transmission or automatic. The high output ISB was rated at 245 horsepower (183 kW; 248 PS) and 505 pound-feet (685 N·m), and only a NV5600 six-speed manual transmission. In 2001-2002 . All that could be heard was just more powerful the diesel was than gasoline. Looks like 235HP and 245HP. With a common rail prior to 2007. Midway through the 2004 model year, the Cummins 600 was introduced, producing 325 horsepower (242 kW; 330 PS) at 2,900 rpm and 600 pound-feet (813 N·m) at 1,600 rpm.
