[@hummerguy]

What do you think about swapping in a LDS multifuel? Seems like it should be a direct swap and they have have 200hp compared to the LDT 130hp and 440 ft Ibs of torque compared to 330

[@tacticalrepair]

That's what I had before this swap. They perform great. The problem is longevity. Mine gave me about 50,000 miles before it shattered a liner and jammed the piston at the bottom of the stroke right in the driveway. When I pulled the oil pan there were large pieces of liner laying in it and the engine was locked up. After four different multifuel engines I wanted an engine that would last. The Cummins is also lighter by a few hundred pounds, cheaper and easier to get parts for, and way easier to upgrade. The lower front end weight is very noticeable while driving. Much nicer handling and acceleration.

[@hummerguy]

@@tacticalrepair What's the best things you think can be done with the multifuel to make it last?

[@tacticalrepair]

@@hummerguy ARP head studs, o-ring the heads, and have the rotating assembly balanced. Still leaves you with the issue of liners shattering though. When that happens at speed, it jams a piston, breaks a rod and knocks a hole in the block. The work I just listed cost so much that you could just buy a 5.9L Cummins instead. That's why I say it really isn't cost effective to rebuild the multifuel anymore.

[@hummerguy]

@@tacticalrepair Another question, would a built NV4500 be able fit with the 5.9 cummins since the engine is 6 inches shorter than the multifuel?

[@tacticalrepair]

@@hummerguy I'm not sure because I don't know how long the 4500 is. It might if you push the engine forward, but then you need to look at oil pan clearance to either the front crossmember or the axle, depending on which way you have the pan installed. You also need to find out what the overdrive ratio of it is. The Spicer is .89-1 ratio, so you want that or lower, like .79 or .69 or something. You don't want to cut your top end speed.

Can you please download the dB meter app, calibrate it, and show us if you're under 90dB when flooring it? Deuce & Guns showed the stock Kaiser motor was 90dB, max (low 80's during idle...yikes), so I wonder if the 6BT is quieter?

[@bladenrexroth2555]

How much torque is going through the trans and t case? Can't imagine it being much more than 450-475 ft#'s?

[@tacticalrepair]

I can't say for sure, but and educated guess would be around 550-600. The older first generation 6BT engines with small turbo, small injection pump and injectors did 400 lb/ ft stock. The P7100 pumped engines were much more powerful, and I've done a little bit with the fuel plate on this one too.

[@bladenrexroth2555]

@@tacticalrepair what were the factory overdrive gear ratios for the 3053a? I'm seeing .86, .85, .83 and .79. How hard would it be to find a trans with a .79 OD or just a gearing swap?

[@tacticalrepair]

@@bladenrexroth2555 the 3053A in the military application have a .89 5th ratio. There are plenty of other transmissions with better overdrive ratio, many of them are five and six speed options from Eaton. Problem is they're all longer and require moving the transfer case back a few inches and then making corresponding driveshaft modifications. Not an insurmountable task, just not something I've had the time and money to do. They're also rated for much more torque than the 3053A.

[@HAHAWTFOMG]

Are you using the stock transmission? What adaptor plate (if any) did you use for the 6bt conversion?

[@tacticalrepair]

Used an SAE2 clutch housing and an SAE2 to SAE3 adapter ring. The stock transmission is SAE3. I could've used an SAE3 clutch housing and just bolted it up with no adapter but I wanted to install a big 14" clutch, which won't fit inside an SAE3 housing.

[@thompsona10625]

Wow! That’s impressive. I can’t keep my truck on the road over 62 mph. The 46” super singles bounce off the highway like super balls. Lol. I’ve gradually increased the number of Dynabeads to 1.5 lb per tire with little improvement in the tire hopping. Are you still running the stock Saginaw or did you swap the transmission with something a little more user friendly? I’ve considered a Cummins swap in the future but the LDT keeps plugging away happily without a care. Has been far more durable than I was led to believe when I purchased the truck 5 years ago.
