Very nice setup. Good luck out there in the wild.

Sorry if this is a stupid question but why don't they just wet sleeve these engines from the factory. It sounds like a better setup, heck that's how all the big rig and tractor engines are done.
Also what is the purpose of adding a deck plate? Just more room for combustion?(I know this may be a stupid question as well lol)
Also congrats on the back to back wins Lavon!

Cummins probably never wet sleeved them because it is cheaper not to. These were Ag and construction equipment engines before running them in pickups. So Cummins probably originally thought they'd be throw away engines. Cheaper is better.
A deck plate puts the compression and the combustion in a stronger piece of material. Cast is very brittle and doesn't do well with extreme heat cycles, cylinder pressure and temperature. The deck plate is made out of steel and is stronger and more forgiving than cast. Putting the ignition in the steel deck plate makes for an engine that will live longer at extremes.

But it's sleeved, I don't think the sleeve cares whats on the outside whether it's a cast block or steel plate surrounding it. Like lavon said earlier in the thread he disassembled a std. 6.7 and the billet rods looked beat up after multiple 2000+ ft lb abuse. What I understand is raising deck height gave the 6.7 combo better rod angles which makes life on everything much easier below the deck.
I'm done being a smartazz, drew correct me if I'm wrong.

Hit on something with a hammer that is .125" thick, then hit on something that is 3" thick. Which do you think will take the most impact?

Compression ratio beat up the rods/bearings. Yes the sleeves care if the combustion is moved up into the deck plate. Sleeve alone still blows out.

With compression ratio dropped to 15-16 would a filled 6.7 block with the same bore sleeve used in this build be as strong as a wet sleeved 6.7 with a deck plate? If money was of no concern I would go the deck plate route without a doubt.

Where did you find power wise that compression needed lowered? I would assume you have found bearing issues with different power levels.

A 1500hp peak cylinder pressure is about the same, whether it has 14:1 or 20:1 compression. O e just requires more care of the tune, so that spike occurres at the proper time.

The deck plate is needed to hold the block together top to bottom. When we remove the stock bore material to install the sleeves we take a lot of strength out of the block. We add the deck plate for several reasons one being, we put tie bolts through the deck plate into the main web so that when the cylinder pressure is trying to blow the top of the block off along, with the cylinder head we can hold the block together top to bottom. The deck plate allows us to run a longer rod, helping to correct the rod ratio, and thrust loading of the piston. The longer rod also slows the piston down slightly, where it turns around, and switches directions top, and bottom this increases strength and durability. As for the question of running the same sleeve thickness, staying STD bore 6.7, and filling the block. I would not want to stand anywhere near that engine when it was loaded up and making power.

Well out goes that idea. I like the idea of having an engine that can handle huge power reliably, the wallet on the other hand won't be to happy I'm guessing

If it's not a dedicated puller, a 6.4L with carrillo long rods seems like a great option for power, reliability, and cost.
