Crazy engine idea

[OldRedFord]

Think a 4-75 or 4-71 or maybe even a 6-71 Detroit Diesel would fit in a bump?

What would it take to do it? Id like to drop a diesel in my next bump.

Man that sounds great! Is that one of the old 2 stroke diesels? At least he isn't Jake braking the hell out of it like they do today. Wonder what tranny he's using? 13 speed Road Ranger in them back then?
Used to be a truck stop on I85 North of Salisbury named that I think.
I bet that thing has so much torque he could put it in high gear and just melt the tires. Or slip the clutch enough and run one heck of a 1/4 mile in it.
My dad was a trucker for 35 years and I rode with him many times when I was young. I drove a Freightliner hood with a 40ft trailer from a rest stop on I85 for about 5o miles before stopping outside of Statesville when I was 15. Talk about something a kid will never forget!
I remember Bob tailing on the W. Virginia Turn pipe and him talking about the torque of the large diesels. An 80's Firebird left the right side booth and was really getting on it to get in front of us before his lane ended. Pop started out in about 4th skipped several got in it again and then skipped a couple more. Made a 5 speed basically and blew the firebird away.

6-71 is a 426 that fires twice for the same number of revs so it is more like a 852. Look up a 12V71T an 852 turbo A friend got one at auction after he condemned it in the Navy. He rebuilt it and put it in a F 350 4 door truck, he moved the firewall to the rear of the front cab area to make room for that monster. He was an engineman in the Navy and worked on all detroit diesels for generators and ship propulsion. His biggest was as big as my F250 in length a 16V2798AT 1000 cubes per cylinder. 768 max rpm.

Yup, it is one of the old 2-stroke diesels. I think its a good thing I do not have much in the way of extra money.

Of course I could just do a Cummins swap, but I like doing things different.

Putting a 382 John Deere in my 73. Probably going 6sp fuller. If I had a 671 (twins in the thompson), I'd build up a 4wd 250!

I was a Detroit/Cummins/Cat technician for about 20 years. Anything bigger than a 4-53 is too heavy for any F100/250/350.

The ones in the YouTube videos are 53-series engines (53 cubic inches per cylinder).

You can see the weights of the popular heavy-duty truck diesel engines here:

I'd also vote for the 53's. A 6V53 weighs around 2300 pounds. The 3-53 or 4-53 would be the ones to use.

What does a 6bt Cummins weigh as compared to a 4-53?

Never knew those DD weighed that much.

[Dragon]

The Ford/IH diesel that was used before the powerstroke added 1800 pounds to the F Series Above what the V8 or I6. Big difference in front springs.

The Ford/Binder engine is called an IDI, 6.9, 7.3. They weigh a tiny bit more than a 5.9 Cummins, around 1200 pounds, an average 5.9 pickup engine weighs 1150. That means they added about 400 pounds over the weight of a 460 with the IDI.

"His biggest was as big as my F250 in length a 16V2798AT 1000 cubes per cylinder"

I was a GSM in the US Navy, nothing I went to school for ever broke so I spent several years repairing the 16V149TI detroit 1000KW gensets along side the engineman. Detroits are simple engines, even simpler than how they operate is determining thier exact size via thier engine model. 16V is 16 cylinders in a vee, 149 is the cubic inches per cylinder, T is turbocharged, I is intercooled. The 149's I worked on are one of the largest engines detroit made. They are made using two V8 blocks and special crankshafts, 16 individual cylinder heads, etc. The only production detroit engine I've heard of larger than the 16V149 is a 20 or 24V149 (I don't recall which). The 149's I worked on (and in) are two stories tall and the size of a couple F-250's.

Detroits have their place. That place is where the need to run no matter what and manage large loads is key. They make excellent large stationary engines in countries where the EPA doesn't exist. They make terrible on the road engines. They are very fuel innefficient, leak like crazy and are god awefully noisy. Those V16149TI's on the ship I was on were rated for 1000KW continuous duty with a meltdown rating of 1500KW (that's a difficult amount of power to actually comprehend). The most amazing thing to me about those engines wasn't that rating, wasn't how #4 diesel could actually burn and leak more than 250 gallons of oil from it's sump in a day, but that one could actually drop valves on 4 of 16 cylinders and still be put online at 800KW load because the other 3 generators all failed to start or dropped offline because of logic glitches that couldn't be figured out or bad air starters.

53 series detroits are not very powerful engines.

The detroit is a GM engine. To pull anything with them you have to drive them like you are trying to blow it up. Oh yeah the nickname for them are "Poor man's diesel"

When I first started driving big rigs I drove a few of them Detroits (8V92T) for a farmer and he told me to drive it like I was mad at it. I enjoyed driving them locally, hauling grain and stuff, but they are terrible noisy, I wouldn't want to do longhaul with them. I don't know the torque numbers but I think that even tough they are rated at 435 hp the torque is nowhere near what the inline 6 Diesels are. I'm convinced that a smaller 300 hp inline 6 (60 Series Detroit, Cat, Cummins) would easily outpull a 8V92t 435 hp Detroit.

Supposedly, the larger a diesel engine gets the more efficiently it can actually run being 2 stroke. Many BIG ship propulsion engines, the largest diesels in the world, are 2 stroke and very efficient. It has something to do with the size of the engine being proportional to the RPM the engine turns and getting everything matched effectively for 2 stroke operation.

Those large diesels are direct prop coupled, they spin very low RPM and run either direction to reverse.

I know guys that love the old Jimmies. They will happily admit the engines make far more noise than power, but they just love that noise. To me, the noise is retching.

They are also known as "Screaming Jimmies" for obvious reasons. My neighbor in AK had a pair of 6-71s on his boat. Every time he fired it up, I couldn't decide which was worse; the diesel noise, the blower scream, or the huge billowing black cloud that left soot all over my boat. I had a Toro-Flo at the time, so I wasn't really any better of a neighbor, I guess.
