I searched but couldn't find anything recent comparing the 2021 6.2L to the Corvette 6.2L.  There is a topic on this for the 2014 6.2L, but I couldn't find anything recent.

 

Since 2014 the 6.2L in the trucks has stayed at 420HP and 460TQ.  I think the only difference in the Corvette back then was the Intake Manifold which bumped the HP up to 430.  But the 6.2L in the Corvette has now jumped from 430 up to 490 and torque went from 460 to 470.

 

So what's different between the LT2 and the L87?

 

Thanks.

Looks like I may have found the answer using Google.  Looks like they went to a new cam with the LT2, in addition to physical changes for the mid-engine installation.

It also as a higher rise intake manifold, supposedly because there is more "hood" clearance.  I've read of people with Camaros swapping to that manifold, it apparantly will fit under a new(er) Camaro hood.

What about the the rest of the internals?  Are they identical?  Or are there differences between them?  Crankshaft, pistons, heads, valves?  I'm really wondering how hard it would be to incorporate the Vette changes into a truck like the ZR2.

 

Thanks.

I’m thinking the 650 hp supercharged LT4 would be a an easier swap.  But I’m not sure of any internals of the LT2 other than the cam.  There are some minor external plumbing differences from what I’ve heard to swap that intake onto a Camaro LT1. The LT2 is a little higher rpm motor and maybe not as suitable for a truck.  The LT4 has a very mild cam and could be an awesome truck motor.

Or just buy a Whipple or Magnuson kit that fit the 6.2 and will bump you up to 650HP without a tune running 5-8psi of boost.

I’m also interested in what else is different? From what I’ve read the crank rod pistons and possibly heads are the same? But as to the rest I don’t know.

A higher rev limiter for the Corvette would permit the higher peak horsepower, too.  Horsepower and torque curves cross each other at 5,252 RPMs.  The rev limiter in our trucks, iirc, is only a few ticks above that.  I think it's 5,600 RPMs.  I believe our trucks are still climbing in the horsepower curve when it's told to stop increasing RPMs by the computer.

      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.

      I went another direction after losing a trailer tire, thanks to not being able to access air at ANY of the 5 gas stations and garages I stopped at prior, with a Toyota Tacoma onboard, 50 miles from the Canadian border. They were either out of order, access was blocked, or the hose a few feet too short and I couldn't get any closer without risking damage to someone's property.   https://postimg.cc/gallery/X5QJ55w
