Has anyone ever wondered why GM decided to kill the 8.1L rather than enhance it? It would seem to me that GM could have used the displacement on demand feature that it is using on its LS series engines and put it into the BBC with spectacular results... Call me crazy, but if my 8.1L had this technology and it was making 15-17+mpg unloaded on the hwy, I'd be thrilled, but then it would start to encroach on Diesel capability a little too mucht? wouldn't it? (Not that diesel isn't superior already for a hauling truck, but it might make alot of people think twice about spending the extra $ since most of us don't tow everyday). Anyone think I'm off base here? It just seems like a logical step to me, but then I'm just a BBC truck guy.A 4.0L 4cyl on the hwy should do the trick,or a 6.0L 6cyl should make up for some hillsor full blown 8.0L when taking off or necessary..Seems ideal,Rob*Not to mention a "hybrid" version of this truck.... to add some additional mileage..

I heard GM shelved the 8.1 for pick up trucks. They still use it in the Kodiak/Topkick. My guess is it had something to do about fuel efficiency? I think Ford and Dodge shelved their V10's as well for the pick up trucks.

When you look at the number of BB pickups, its hard to make the economic sale for the BB to get major R&D funding. Its just not a high enough demand/profit segment for GM to put money into. Maybe if they were better off they could of, but look at all the other platforms that GM has put on hold or killed off to stop spending money. Not saying it would not be a great idea, just not enough money in it for GM right now.

I personally would love to see the 8.1 put into the new camaro coming out this January, and add a SC to it! Who knows, maybe GM will do it in the next two years after the Camaro comes out. That is when I plan on getting the Camaro SS, 2010 ish.

I thought the Ford V10 was still available. DEWFPO

 

 

I 'm almost positive it is too.

 

 

 

I heard they shelved it cause of gas consumption. I'll check in a bit.

A freind of mine was saying something about gov. regs. he said no new engines with over 4" bore. Hes a service mgr at a dealership. (BMW) not sure what thats about. I have a 8.1 with Allison 1 ton at work. I love it. Im looking for another one. 2006 one ton dually mason dump. We are a municipality in N.J. The friggin D.E.P. is making municipalities retrofit all diesel refuse truck with particulate traps regardless of year. And they are making us file a form listing every motorized vehicle of any kind with a diesel. Obviously they are creating a file for more extreme regs in the future. So, I'm just not looking to buy any new diesels. I also talked with a manager in another town who has two identical F-450's one with and one without traps. He said the one with the trap is a pathetic dog. uses more fuel cant pull crap. N.J. is over run with tree hugger liberal egg heads and the dep is the department of environmental protection. scary stuff. too much power...too many eggheads...costing the taxpayers billions of dollars for questionable gains to the environment. I dont know why everybody is after diesels but Im not buying any till I find out where its all going. any way I love my 8.1 and my 6.0 in my personal 3/4 ton.

Mike,

I agree with you, I love my 8.1L.. soo smooth, quiet and power on tap at will. Diesels are nice big haulers, but for what I do with the truck it didnt' make since to spend the extra money for one. I'd also love to go with nat'l gas for the truck, but I'm having trouble with that (see my other post). Anyway, thanks for the replies guys. I understand GM is in a pickle right now, but I guess I didn't think that it would be soo difficult to add the system onto it. Its a cylinder head and computer issue, not a comlete redesign.

 

Thanks for the replies.

ive heard of something even better than LNG,although there was a guya few years ago racing a truck running LNG and just had it perfected. plugs last forever no soot of any kind. the oil stayed like new. but the latest thing i heard was a hydrogen injection system. fuel cell in the bed and sort off a nitrus system hooked up. the claims were over 20 mpg in a 3/4 ton pulling a trailer. i like the idea of retro fit tech that we can use on exsisting motors and use less gas. anywya seeya.

I think that is just complete bullshit! If they want to make strict regulations for diesels, thats one thing, but to go after diesels long obtained before the restrictions is just wrong. They should be grand fathered in just like 60's era muscle cars. This whole diesel thing started in NYC with the buses, those tree huggers complained about it then and there and Bloomberg heard them. Just like the smoking ban started in NYC, and the fatty oil ban. I always had a feeling diesels were one day going to have emission control in NJ, it was only a matter of time. It's places back east in NJ like Newark and areas by NYC where pollution is known because of all the big rig's they want to make cleaner.

absolutely right on. The DEP is ruining N.J. in the interest of making it pristine. Places like Newark recieve millions to help buy new equipment and meet regulations and the suburbs have to pay for it..then we get hit with regs even though we already live in the rural part of the state and guess what? no money for us from the state! people and buisness have been running out of N.J. for years and the polititions are blind. Hard working blue collar people cant servive. They have been moving to PA for years. the vacume is being filled with low income workers. I went to a local aggregate and cement dealer when I saw an ad for an operator. They needed someone to load trucks, bins and their cement factory. They have a big John Deere, I dont know Jon Deer numbers but it was 966 size. The guy asked me what I needed and when I told him he said ..You dont want this job...I asked why and he said he was only autherized to pay $12.00 an hour! no bennifits...Thats in Hunterdon Cnty. one of the wealthyest counties in the entire nation. If you worked 20 hours a day you couldnt live here. A teamster operating the same machine would be around $30.00 before benies. The libs in N.J. want our money so they can give it to someone else..they want our guns so we cant shoot the bastards they let out of jail too early. they want our trucks because they all drive priusses. they want our jobs so they can give them to illegals at 1/3 the wage..i have to pay for so many other peoples kids to go to colledge free i cant afford to send my own kid without borrowing money..hospitals are closing down under the load of people walking in for free care in the emergency rooms. and on and on. ive been leaving here since i was 18 but family and all have kept me here. im 52 now and im still leaving. thing is when i finaly leave it will be the do-gooder libs supposedly helping everyone who pushed me and all the other working people right out of the state. Hows that for a rant?

Yes, moved from Union County. guess what, you forgot to mention something about NJ. Not sure if you know this but if you are a NJ resident and plan on moving out of state, NJ charges you a 1% penalty for moving out of state. One of my clients who was moving back to Texas told me this over the summer. NJ is so messed up! Another thing that gets under my skin is NJ charges a sales tax on ATV's and even lets you register it so you are legal to ride on trials out of state, but yet won't provide any state owned land to let you ride your ATV. I heard today at the lawn mower repair shop that the next town next to me (Tewksbury) their police department bought two ATV's and paid extra money to have them modified in order to chase down illegal dirt bike and atv riders who trespass on private property. Tewksbury is so expensive to live there, they charge alot of money in property tax a year. One of my customers pays over $30.000.00 a year in taxes for 8 acres. Grant it he has a huge estate, but still..

      2027 GMC Sierra: Official Discussion

      It wouldn’t have happened if the government hadn’t mandated outrageous fuel mileage standards. It does very little for the consumer. It adds cost. Back during Covid there was a chip shortage. They gave a rebate for your truck if it didn’t have the chip to turn on cylinder deactivation. It was 50$ because at best you may see 1/2 a mile increase per gallon. Splitting hairs each fuel mileage trick wasn’t mandated. The government doesn’t do the engineering work and say use this until it’s already in use and they like it. The fuel mileage was mandated. And those add ons the results. There’s a mandate and they are the results.

      It was never mandated.  Ever.    Automakers were incentivized to install it by getting CAFE credits to help with their vehicle fleet fuel economy scores.  They were being handed money/CAFE credits to install it.  Which is NOT a mandate.       The current admin removed the incentives that were behind them installing it.

      5 Best Slide Down Gameplay Tips! 

      By lanaderay · Posted

      Are you playing Slide Down endlessly but your score is still low? Are you constantly crashing into obstacles as the game speed increases? Don't worry, this article will share 5 invaluable tips to help you master the race and impress your friends. Golden Rules 1. Look one step further. The mistake of 90% of new players is only staring at their character. The secret of experts is to look towards the top of the screen (where the slide is about to appear). This gives your brain an extra 0.5 - 1 second to process the situation and determine the direction of movement before the obstacle approaches. 2. Use gentle movements; don't swipe too hard. Slide Down is very sensitive. Moving your finger too forcefully or with excessive amplitude will cause your character to be thrown off course or crash into a wall. Practise moving your finger with small, decisive, and precise movements. 3. Don't be greedy for gold in dangerous locations. Gold coins are tempting for buying skins, but life is more important. If you see a gold coin right on the edge of a cliff or next to a spike trap, ignore it. Our goal is a High Score, and your score only increases if you survive. 4. Make the most of Power-ups. During the slide, you'll encounter items like Magnets (attract gold) or Shields (temporary invincibility). Never miss them! Especially the Shield, it's your "get out of jail free card" to help you get through those deadly fast sections. 5. Stay calm when speed peaks. When your score exceeds 500 or 1000, the game speed will be very fast. At this point, don't try to think logically; let your natural reflexes work. Take deep breaths and don't panic. Apply these 5 tips to your next game, and your leaderboard will surely improve dramatically. Good luck climbing the Slide Down leaderboard!

      Why I Recommend a Desiccant Air Dryer for Cleaner, Drier Compressed Air

      By lingyuair · Posted

      If you use compressed air regularly, one problem you cannot ignore is moisture. Water in the air line can cause rust, unstable air pressure, poor tool performance, and even damage to sensitive equipment. That is why I highly recommend using a desiccant air dryer. A desiccant air dryer is designed to remove moisture from compressed air by using drying materials such as activated alumina or molecular sieve. Compared with basic water separators, it can achieve much lower dew points, making it especially useful for applications that require dry and stable air. For workshops, painting systems, pneumatic tools, CNC machines, laser cutting equipment, and industrial production lines, a desiccant air dryer can make a big difference. It helps protect equipment, improve air quality, reduce maintenance costs, and extend the service life of the whole compressed air system. Another advantage is reliability. Many desiccant air dryers are built for continuous operation and can maintain stable drying performance even in demanding environments. For users who care about long-term efficiency and equipment protection, this is a smart investment. When choosing a desiccant air dryer, I suggest paying attention to air flow capacity, working pressure, dew point performance, regeneration method, and maintenance requirements. A good model should match your compressor system and actual air consumption. Overall, if moisture is causing problems in your compressed air system, a desiccant air dryer is definitely worth considering. It is practical, efficient, and highly useful for anyone who needs clean, dry, and reliable compressed air.

      My brand new 2007 Silverado's wax frame was rust from end to end partway through it's SECOND winter here in MA. That stuff is completely useless.
