skinny 02-07-2005, 11:12 PM Has anybody notice the difference in torque numbers for the lly between Chevy and GMC on their websites. Chevy 310/605 GMC 310/590 What GMC ownershttp://www.dieselplace.com/forum/images/smilies/rippedhand.gif don’t get the extra 15lbs. of torque. Whats the deal? http://www.dieselplace.com/forum/images/smilies/confused.gif misprint or true? earthcrusher 02-07-2005, 11:24 PM I went to gmc.com they show 605 lbs. torque. 520 for the manual trans. Reineke 02-07-2005, 11:43 PM Either way, It's still the same engine...310/605 with auto skinny 02-07-2005, 11:50 PM It must be a misprint on the specs page for the GMC NCMIC 02-08-2005, 06:13 AM Well, they may have forgotten to change it on the specs page, if that is where you saw it. The 04.5 LLY was originally 310/590 and then the 05's got a new software load making them 310/605. I don't know if the reflash will correct the ratings for the 04's. But as for me, I still love my truck, even if it is on a diet, 15ft lbs lighter. duramaxgoose 02-08-2005, 06:39 AM duramaxdiesel.com still shows the lb7 info, they need to update there site yamahagrizzly 02-08-2005, 07:02 AM theirs absolutly no differnce in accual power at the wheels. at the dyno their was an 05 and my truck my truck put down 2 or 3 ft lb more than the 05 with 605. the numbers are on paper thats about it. | ||
