  2. 2500Hd Rumors

    I think that GM will offer a gas option for the 4500/5500, and I think it is likely the L96 will be replaced in the 2500/3500 at some point, my guess is with the same engine in the new medium duty trucks. A lot of large fleets are going back to gasoline, the economics of diesels no longer work out for them. Sure diesels have a power advantage, but they no longer have a fuel economy advantage, they are less reliable than gasoline now and the are VERY expensive to fix. Also, gasoline engines are easy to convert to CNG/LNG.
  3. 2500Hd Rumors

    First off, regarding the Ford 7X engine: Basically the story is that it is a tall deck long stroke 7.3L derivative of the current Ford 6.2L. 7X is supposed to replace the V-10 in the F-450 and larger trucks, so it may not be available in any Ford pickup. Now, about a replacement for the GM L96: The answer to that question may be found in the Silverado 4500/5500. The new Chevy medium duty trucks will go on sale later this year, but initially only with the Duramax/Allison powertrain. However, with the resurgence in gasoline engines for medium duty trucks, I think it's very likely that the 4500/5500 will eventually have a gasoline engine. In fact, some of the 4500/5500 prototypes that have been photographed have NOT been diesels. It is a fact that Freightliner and Isuzu both use the L96 6.0L engine in some trucks up to 19,000#'s GVW, but the story that I hear is the L96 will not be used in the new GM/Navistar medium truck. The new Silverado/Sierra HD pickups are supposed to debut in 2020, which is about the time I expect to see a gas engine in the 4500/5500.
  4. I am hearing a bit about that new 7.3L Ford: Looks like it is going to be a tall deck version of the 6.2L, and it's probably going to replace the 6.8L V-10 with the 6.2L staying for the 250 and 350. I am VERY interested in the upcoming GM large V-8. Rumor is that it's going to be something of a 'Big Block' LS. I would guess it will be E85 and CNG/LNG compatible. DI is pretty much a given for emissions.
  5. That's what I am thinking. The clay bar should remove raildust (and has every time for me), and if it's gone the condition should not reappear. Has to be something getting back on the paint.
  6. I have a '12 GMC 3500HD with the L96, been a great truck. Still has low miles. I have not decided yet if I will get a 2019 with what should be the last of the L96's or wait for what may be coming in 2020. I figure we will learn a lot about the new engine before it's too late to get a '19.
  7. I work for a large fleet, and we have a lot of '07-up Chevy 6.0L's and a good number of Ford 6.2L's. We don't tow a lot with these trucks (3/4 ton) other than arrow boards, small welders and air compressors. The performance between the 2 is very close, but I would say the Chevy's at least feel a little faster. The L96's are extremely reliable, the only problems I see with then are broken exhaust manifold bolts and water pumps once in a while. The Ford 6.2L's are a lot better than those junk 5.4L 3 valve mods., so far so good. Considering the whole truck, I think 2011-up L96 GM 2500's and 3500's are the best all-around large pickups. There's a lot of talk about the upcoming Ford 7X engine, it will be interesting to see what it is. From what I understand, it will replace both the 6.2L V-8 and the 6.8L V-10. But, what is even more interesting are the rumors I am hearing about a new large V-8 from GM. Story is it will be used in the next generation HD's and the new Silverado 4500 and 5500. My guess is it will be direct injection and will have the new 'Random Skip-Fire' AFM system, which should be a lot better that currect AFM systems.

  9. Most of the newer UPS package cars in Southern California are on Freightliner chassis with L69 6.0L gas engines. One interesting feature is the 6.0L's are mated to Allison transmissions.
  10. Interesting! I have heard 2 rumors regarding the Ford, one is that it's an enlarged 6.2L, the other that it's an all new pushrod engine family that will replace both the 6.2L V-8 and the 6.8L V-10. That later story may indeed be true, I heard some time ago that the 6.2L V-8 was intended to replace the 5.4L 3 valve and the V-10, but had durability issues in testing for the 450 and larger Ford trucks so the V-10 stayed in production. As for the new GM engine, this is the first I have heard that it may be something other than a tall deck LS of some type. Can't wait to hear more! In any event, with the increasing popularity of gasoline, CNG, and propane fuels for commercial vehicles, it makes sense for both GM and Ford to develop new engines for this market. GM in particular, as they will likely supply to Navistar International as well.
  11. Those are the diesel engine options for the Isuzu-built Chevy LCF's. The Navistar truck will debut with the L5P 6.6L Duramax. A gasoline option may be available a year or two later.
  12. There are a couple of bogus automotive websites that post these types of speculative articles. The grammatical errors lead me to believe they may originate in China, but who knows. Sometimes they do get a story right, but this one isn't. Anyway, there very well could be replacement for the L96 6.0L coming, perhaps as early as late 2019 for the 2020 MY. Ford is working on a 7.0L+ gas V-8, and I wouldn't be surprised if GM is thinking along those lines as well.
  13. The 8.0L is a stroked L19 'Vortec' 7.4L Mark VI Big Block. That engine is also marketed to other OEM's through Powertrain Integration, and Freightliner uses it in their S2G propane-fueled medium truck: https://www.fccccommercial.com/chassis/s2g/ The propane 8.0L is also available in Thomas school buses. The 8.8L is a version of the Vortec 8.1L Mark VII Big Block. It has the redesigned cylinder heads of the 8.1L, and it is manufactured and marketed by Powertrain Solutions Inc.: http://www.psiengines.com/ Although I think International may be expanding the use of the PSI 8.8L in their large trucks, I don't think either the 8.0L or the 8.8L is what is coming in the new Chevy Silverado 4500/5500.
  14. Let's straighten out a few things: First, International (Navistar) has NOTHING to do with Ford anymore. Some IC (a Navistar company) school buses use a PSI 8.8L gasoline/propane V-8. This 'Big Block' is a modernized and larger version of the old 8.1L. This 8.8L may start showing up in some International trucks next year. Bluebird school buses offer a propane Ford 6.8L V-10, but no International bus or truck ever came with the Ford V-10. Now, about this new Ford gasoline V-8: It is supposed to replace the 6.8L V-10, will be around 7.3L, and should debut in the 2020 model year (late 2019). Beyond that not much is known. So, what about G.M.? Well, that's an interesting question. Yes, Chevy will start selling medium duty 4500/5500 trucks again next year. The trucks are the result of a joint venture with Navistar (and International dealers will get their own version of the truck to sell). These trucks will debut with the L5P Duramax/Allison drivetrain. Word is that these trucks will eventually offer a gasoline/propane/CNG V-8 engine. Rumor is that it will be a new large displacement V-8, not the current L96 6.0L. No idea if this rumored engine is a Big Block resurrection or based on the LS. So, it's safe to say that GM will need a larger gas V-8 in the near future, just like Ford does.
  15. I am hearing from a reliable source there will be 4X4 models. I have heard very little about the specifics of the International version. I do believe the spy photos we have seen so far are of the International based on the design and shape of the grill (close resemblance to the DuraStar). It may not be all that different from the Chevy. Last I heard the International version will be called the 'CV' series, in line with International's new truck series designations. To sum up, these are my 'educated guesses' regarding the new truck's features so far: Straight frame rails, I-beam front axle on leaf springs. Modified Silverado cab, composite tilt front hood/fender assembly (great feature, just like a medium/heavy truck). L5P Duramax/Allison drivetrain exclusively at introduction. Not exactly sure what model of Allison or how many speeds it will have. Rumors of a gasoline/CNG/LNG engine option a year or two after introduction. Chevy version will be named Silverado 4500/5500. Not sure what the max. GVW will be of the 5500, but based on what I have seen in the spy photos I would not be surprised if it went to 25,000#'s GVW like the previous TopKick/Kodiak 5500 did. Crew cab versions very likely. Good chance the Chevy version might debut at the Work Truck Show in Indianapolis on March 6, 2018. The trucks will likely be 2019 MY and go on sale a bit later in the year.
