Detroit in Allis 440

I would think that a 6V92 would be a more viable option than a 6/71. But I really don't know how hard it would be to adapt it. Have more power also, but not so much it would tear things. Uh, maybe.

6v71 is almost bullet proof. 92 series had their fair share of issues.

440 will take 350 hp. Same finals transmission and drop box as Tiger II's. Buggest difference is that the frames on 440's and bearcats arent has heavy. Steigers moto was 100lbs per hp un balasted. So a steiger at 325hp should weigh 32,500 lbs.

An 8.3 Cummins will fit in it without stretching it I beleieve

I agree with Dan, I wouldn't want an old "screamin jimmy" in tractor personally,well except an oliver 1900. Them detroits had to wide open to pull anything. Plus I wouldn't want to listen to it scream all day.

I have a cummins in my case 5240 and I would take that over a detroit any day. It would wipe the floor with that detroit 72 serries we had in our truck.

I'd take a 555 over a 3208 any day of the week...We have one in our 555 versatile and as long as you don't pull it like a 275 HP 4 WD you will be fine...I wouldnt have a slobbering Detroit in a tractor especially a 440 Allis with as noisy of a cab as they already are. No v8 is good but the 555 is about as good as they get in that size of a tractor

Ive seen two transplants over here ,one with a 6v 53 detroit and another with an 8.3 cummins.

That tells me all I need to know on the Detroit, I'll scratch that. We have 12 machines with cat engines and 2 with cummins. One is a tractor with an 8.3 that dad bought new and it broke the crankshaft at 1200hrs. The other is a N14 in a semi that has been to the shop 7 times for injector fault codes and $5000 later it's still not fixed. The only problem we've had with a cat engine is a heui pump went out at 7200hrs. We have 2 dump trucks with 3208's and they may not be a powerful truck engine at 54,000lbs but they will start at zero degrees as soon as you hit the switch. I just thought if I could get an extra 100hp from a engine the same size it might be worth it if the noise level wasn't too bad. I haven't even got a chance to run the 440, because it seems to have some stuck valves and it was parked for getting coolant in the oil.

Oil in the coolant...I know that feeling. The Cummins V8 was good for that. Terrible cavitation issues. That's why our V504 is apart. But, a little JB weld in the pitting and new sleeves and orings and we'll be back in business soon!

I've had no problem getting parts for the 504. Most parts are the same on a 555. Only thing you have to remember is your putting a bigger engine in the same tractor you pulled the triple nickle out of...The rest is still only rated for what it was build to handle

how about that 640 v8 perkins

HudCo, you must really want to make a guy unhappy!  I've heard the Perkins V8 makes an excellent boat anchor....
As for the Detroit, I've been told and maybe read on this forum, that the only way to run one in a truck is to start up the truck, let it warm up for a couple minutes, take a good sized hammer out of the tool box and slam it onto your thumb as hard as you can, then drive it like you feel!

The semi I have has a 6V92 TA Detroit in it, it is a little noisy but not as bad as what was in the older Olivers (or my HD-5 crawler) that are naturally aspirated.  It does have a muffler though which helps a lot compared to a straight pipe.  A 4 stroke will have more torque and will be quieter, but you need to like and understand the Detroit diesels in order to tolerate them in equipment.  The turbo does help to significantly quiet the engine noise, but it will be loud enough yet.  My truck doesn't have the greatest of noise dampening (1980 L9000 Ford) and has the "doghouse" in the cab to get the engine noise a little closer to you also.  Looking at the 218 engine HP of the 440, the 8.3 Cummins will comfortably make that and more for a long time.  If you straight pipe it and it is like the 8.3 in the R series Gleaners or the IH combines you'll have just as much cab noise as the Detroit.  When the neighbor starts his 2188 in his shed a 1/3 of a mile away, I can hear it at my place.  I'm so happy in the fall when he is done running the two closest fields to me so I can sleep again (work 3rd shift).  The 6V92 TA Detroits make pretty good torque down to about 1400-1500 RPM unlike the older natural aspirated 71 series Detroit.

You must be a very light sleeper. I work shift work and if the help is running the FW30 with a straight piped VT 903 it doesn't wake me. The 903 can be heard 3 miles away.

One of the best sounding trucks I ever heard was a 903 no turbo with straight pipes. Sounded just like an extremely healthy V8 Chebby only louder.
