detroit 2-71 engine

i just bought a pair of 2-71's at scrap price and would like to put one in a working early '50's tractor. what is a good candidate for a 60hp gutless SCREAMER? the noise appeals to my deaf ears. a farmall M is common around here.
 

90HP no problem at 2300rpm with N series Pistons , N series sleeves and C 80 injectors. Upgrade the valve springs and cam follower springs to the latest Detroit Diesel heavier spec.
 
LOL, We had one in a crane truck. Was a great crane when on the job. Getting there was a different story. You could take off from a red light and be in 3 gear before you went under the light. You can hear them coming from a mile away LOL. Great old iron
 
Does Detroit Diesel even support the two cycle engine anymore (parts)? The Manual for the two cylinder is by itself. There's a 2-71 manual. bjr
 
An M with 560 rear bearing upgrade and a 1:.66 gear reduction between the engine (or a truck 4 speed) to make it long enough to fill the frame. Jim
 
Maybe , BUT the first hill or tough spot they will wither like a littel girl when she see's a spider . Ran enough of them back in the day hauling coal . you would come home at night after putting in 14-18 hours and your right arm and shoulder would be screaming at ya from all the shifting you did in a day . One year old trucks with the shift tower plum wore out and needing a rebuild.
 
Two cycle Detroits are not luggers and were never intended to be but no one else could put anything near that kind of HP in similar CI and package size. And, of course, they run forever.

We have an old forklift at work with one of those in it and it sounds like it's tearing the world up. Not real strong, but sounds cool and never breaks down.

Well, I've got a '71 Chevy C90 with a 6-71 Detroit. Several years ago, the pulley/belt assembly that holds the fan let go and the fan went through the radiator.
I had one heck of a time trying to find a parts book from Detroit because all the Detroit parts men were all about 20 years old and they whined and cried about how they couldn't find it anywhere.
Chevy was totally useless also. The best place to get parts for these is the aftermarket.
 
60 horsepower out of two cylinders aint at all gutless. They are loud though! I got a big muffler on mine and still need earplugs and ear muffs. I have a 2-71 in an Allis HD5 and am quite pleased with it. That little machine can do a whole lot of work on a gallon of diesel. Mine always starts and its also easy to start when you run it out of fuel. Parts are cheap and been easy to find, would make a great motor in a farm tractor, just keep the ear protection on. I like 'em. JBD
 
I don't want to be a smart #$% but I don't think you can get 110 Hp, out of a single calendar Detroit with 71 cubes in the hole. Years ago we ran the old 671 Detroits and they put out 238 Hp. Then we got the new 8V 71 and it was supposed to putout 318 Hp. Well I would be going along OK and then some kid with a 238 would pass me like a pay car passing a bum. Then he would get on the CB and say " I hate to be mean and pass you guys with the 318 but I am running late and it's hard to make time with a 238.

2300-2500 rpm with the N piston/sleeve, valve spring/cam follower spring updates & C90 injector upgrades. Cam advanced , blower over driven, low restriction muffler and dry air filter.
Many of those 318's were governored down to 1800-1900 rpm. They would top out and be forced to up shift just when they were really starting to pull at 1800-2500rpm.
