Why Not? It is the joy of fabrication to build and make something work by your hands. Plus Detroit 2-strokes make great conversational pieces and sound awesome.
They also brought industry and trucking to where they are today. Dirty leaking devils but they worked and continue to work. But it drove someone to design a 4 stroke to perform the same. Just like 2 stroke dirt bikes they drove people to make a complicated 4 stroke perform the same.
And now the EPA is trying to push all two strokes out the door and into the landfills.
As to the original question, Detroit Diesel, Cummins, Cat or Perkins Diesel all have motors that could be swapped into an F series.
There are several other engines that could also be cantidates for a conversion.
Some will be easier than others to swap in.
Some may even be better than the International motor.
Since each one will require custom fabrication to install it with custom wiring to make it work I do not see any of them as good cantidates for a vehicle that you depend on every day.
There will be parts that may be available, but not common enough that you are going to be able to walk into most part houses or salvage yard and walk out the door with the part in your hand.
Also you have to look at a lot of things when you do a swap like that.
Yep lets drop in a 3406 Cat, 400+ HP torque over 1000 foot pounds max RPM 2100.
So instantly, my top speed is 52 MPH with 3.55 gears on 33" rubber with my 4 speed.
So now I need an overdrive or double overdrive tranny if I even want to think about any kind of MPG while driving at modern speeds since a 3406 is not a very economical engine to run at max RPM.
The next thing that happens will be the drive shaft will turn to limp spagetti at the first steep hill when all the Cat torque turns it into a pretzel.
The upgrades to keep from breaking parts will cost more than a new truck after a few years.
I had a friend here that had a 3406 in his F350 15 years ago.
He finally took it out because he was tired of getting his truck towed home every time he drove it.
Every time he mashed the throttle it was a twisted drive shaft, broken axle, clutch or U joint.
Fabrication....I bet he had 200 hours in making parts to mount the engine, tranny and transfer case as well as the linkages to make the throttle, clutch and shifters all work.
Yes it was very impressive to look at, even more impressive to hear running.
But parts falling on the ground when he mashed the throttle took a lot away for the overall impression the truck made on you.
If your goal is car shows and Sunday cruising that is one thing.
But if you are looking for dependable transportation that can be used for work, find something that has an established parts base all over the country.
If I bust my transmission tomorrow, I can have a four, five or six speed out of a salvage yard back in it Saturday.
With custom fabrication of something like a Cat motor would require, I could probably have somthing back in in two or three weeks.

When I was a kid I remember riding in the old Greyhound buses, the smaller city busses that had detroits in them. I don't know if they had 3-71's or 4-71's in them but they only had a 4 speed transmission and used to get along pretty well. The shifts remind me of the T-19.
I have had the truck a few months, and have upgraded the axles, brakes, and power steering.
It is now a very capable, strong, reliable, and unique truck. I just got back two weeks ago from a 7,000 mile road trip in it, absolutely no problems, in 7.5 total days of driving. I even hauled a 6-7 thousand pound truck from Washington state to NY.
My truck has a RTO610 Roadranger 10 speed overdrive, and I would not be happy with any fewer gears. It is geared for 75mph at 2,100 RPM, I start out in 3rd, 4th, or 5th most times, but the lower gears are handy for hills and when loaded.
if you are still considering a swap like this I think you should plan on axles that are up to the task, and brakes too.
I am building a 48 Chevy 2 ton with a 4-53TI to be my daily driver, it has an RTO6610 and 13" disc brakes.
My ford is for sale, I bought it to play with, I am done playing now and ready to continue work on my Chevy. so if anyone is interested in the Detroit powered Ford make me an offer. Pictures http://community.webshots.com/user/Grigg3
You dont want a 4-53, heads are getting impossible to find. 6v-53 too much of a screamer. A balanced and turboed 3 or 4-71 would be ok, lighter too. Look in old airport ground power generators, lots of 3 cylinders being thrown away. we scrapped 10 at work not 2 months ago. I can give you some tips to turn them up pretty good too, as others on here can too
91 f 350 cc 4x4, 3:55 gears. zf 5, 7.3 ATS 093 with bigger comp wheel, intercooled with cutdown 7,3 ps IC all gauges ignored with good aftermarket ones. Head studs, balanced . 12 psi 1k pyro under load way better mileage than the 460.
for around 3-6 grand you could pick up a crown school bus with a 6 53 or 71 detroit & an allision tranny which is what a buddy did to convert to a pretty nice MH then you would at least have part of what you need heap cheap
May I post the pic of your 6v53TT on the DetroitDiesel site?
Looks good with the late model center bolt Al rocker covers and the twins.
Sure, Please do.
I'll see if I can find my way over there again. Last time I thought the threads were hard to follow or understand, at least they were not in order and viewable all at once like these threads are.
I have seen over a dozen Detroit conversions in pickup size trucks. I have owned a 73 1 ton Chevy with a 4-35T, drove it home from CO to VA. I presently own a 6V53TT in a 61 F350, and have put over 11,000 miles on it in less than 4 months.
I am presently building a 48 Chevy 2 ton with a 4-53T with Jakes and a Roadranger RTO6610. This truck will be my daily driver when done, and absolutely no corners are being cut in the construction of it.
So, after working on these trucks, owning several other Detroit engines, seeing countless others form of all series, 53, 71, 92, 110, a few 149, and a pair of 51 series, I have a pretty good idea of what will fit and work in a pickup sized truck.
First, the 92 series are much to big and heavy to fit. I suppose it could be done with allot of work with a torch and welder, but I don't think it is a wise idea. You would need a substantially heavier front axle, and brakes. I have never seen or heard of even the smallest 92 , a 6V92 in a pickup.
A 3-71 or a 4-71 will fit, and work, and I have seen a few.
I think to be useful you will want a turbo on either, and plenty of overdrive and or tall tires to give a reasonable road speed.
In my opinion a 4-71 is just a bit to big to work nicely in a pickup. A 3-71 is still a little tall and heavy for the power it produces, so not on my list of good swap ideas.
53 series, I think the ideal engines for pickup truck swaps.
Starting at the bottom, 2-53 is probably only good for the smallest trucks, like a Toyota looking for mileage and not performance. I have never seen a swap with a 2-53.
3-53 with no turbo is acceptable for a practical work truck, not very strong, and therefore best for local driving. Easy to fit in most any truck.
The aluminum 3-53's easy to find and reasonably priced would be good for 1/2 ton trucks with out needing a heavier front axle.
3-53 with a turbo is better, but if you want power step up to a 4-53T.
The ideal swap in a 1 ton pickup, in my opinion, is a 4-53T. They fit with minimal hassle, have plenty of power for both interstate driving, and towing. They are just on the limit of what a 3/4 ton front axle wants to carry, and OK with a 1 ton axle. Fuel economy is good, not to heavy, not to big it's hard to work on in a PU engine compartment.
The 6V53 should only be considered for 1 ton trucks after about the mid 50,s as they don't really want to fit in the narrower trucks before that, and less than 1 ton won't carry the weight.
I would not recommend a 6V53 for a truck you use like a car, but if you use a truck like a truck most of the time, it's got the power.
A 6V53 is just big enough and heavy enough to make it a difficult swap, and just more than a 1 ton axle wants to carry.
for a full sized plus work truck with upgraded brakes and axles it makes sense, but anything smaller I don't think is a good idea. Turbos are nice....
I have not seen or heard of a 8v53 swap, but it will require substantial firewall modification, and is probably to heavy to even try with a 1 ton front axle. I don't think it would be a good candidate for swapping in a PU.
Please note, these are just my opinions and thoughts after seeing, driving, owning, and building a few Detroit powered truck conversions. You don't have to agree with me, and if not them please present your argument in a nice fashion, I'll probably even change my mind on some things after seeing more and different conversions.
Did you add the turbochargers to the 6V-53 (which ones did you use?)
I have toyed with the idea of putting a 6V-53 in my 55 F-600.
With an over drive transmission and the 5.83:1(high range) 2 speed axle I would get around 2000 @ 60mph.
I have thought that the 6V might be a little too wide though. I really like the idea of using a 4-53T. They went all the way up to 200hp if I'm not mistaken.
A good friend of mine in Ca put a 4-53T in a 1 ton IHI truck with a huge service bed on it in the 70's. It had a 4 speed with a separate over drive. He claimed 15 mpg with it. He put over 400,000 miles on that thing!!!

Note that you can "group by topic" when viewing the message list on the DetroitDiesel Yahoo group site. This will list the topics wherein you then click on the topic and the original message and replys to it are grouped all together. It makes it much easier to follow.
We'd like to have you there as swaps are a common topic of interest.
I just rejoined the Yahoo DetroitDiesel group. It had been so long sense I last visited that they kicked me off. Still trying to figure out how to use it, I got the "group by topic" button, but I still don't like it. I want to see what all the available threads are and then choose one and be able to read it from start to finish. Once I figure things out I'll post about my trucks with 53 series.
