Thoughts and ideas on 16v71 swap

I have a chance to pick up a 16v71(don't know NA or T yet) with low hours to swap out of my 8.2 NA 175hp with. I am already dealing with no mechanics around that want to touch my 8.2 unless I call boat mechanics so I assume I would have even more problems with a two stroke? And I am not above going to a college to learn what I need?
WHAT DO YALL THINK? Good swap or not?
A lot more horsepower?
Will my AT545 bolt up sae3 bell?
Tranny cooler a definite either way.
I said hours caise it is on a heckuva generator that has never been used? Only maintained and test ran monthly so I know I would need to verify exact horsies it was built for.
Tell me I don't know what I am looking at or whatever?
Let me have it

Not that transmission. Needs to be stouter. Just wait for it....

Another bus is what you need, my friend. a parallel platform.

That would be an amazing swap! However, you'd need to extend the nose of your bus out another 4ft. Those things are probably around 8 feet long. Are you sure it's not a 6v71? That'd be more likely to fit.

(Ok, maybe not 8 ft.. but they sure are long)

Not beyond my abilities to pull a TANGO and do a whole refit if it was to upgrade what I have. My hood has sprung hinges I am going to replace anyway?
The one I can get for 1000$ is a 16v71.
Rusty. A new platform is out of the question for me?
I bought what I bought?
I built it out for what I wanted at the time and yes my kids are grown and almost gone and my wife has dreams of turning there bed area's into desk work spaces?
Our dream is to get back to Texas even if it is at 49 MPH and live in the bus while we find land and I build our home. but if I have a chance to get a better powered engine than what I have before the trip to get MPH then I am going to go for it.
I know tranny upgrade,rear gear upgrade and all of that. My 8.2 175HP still starts and runs great at the drop of the hat and I am keeping up with tranny upgrade's and I am looking at rear gear upgrades and if I do a motor swap I will definitely be changing to a 2-speed rear end. So I have low end when I need it and high end when I want it

cant you just turbo the 8.2 and turn up the smoke? and swap in a Built allison 1000 like i did mine?

seems then you'd get more horsies, and more hoofs on the ground instead of spinning rouind on the merry-go-round (torque converteer unlocked)..

Dude, you totally NEED a bid two stroke Detroit.
DO IT!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !!!!!!!!!!!!

I think one member has successfully swapped a 6v71 into his bus. Maybe up the ante?

A 16V71 is going to be twice as long as your current engine, weigh 3 times as much, will immediately blow your transmission to pieces if you can get it hooked up (700 HP at least) and will get 2 mpg on a good day. Are you sure it is not a 6v71?

Meanwhile, back on planet Earth . . .

And I trust you're thinking about the cooling system (Detroit 2-strokes make LOTs of heat, and it has to go somewhere), and a transmission and axle that can handle at least 1500 ft/bs of torque, and frame rails and suspension that can cope with the weight of a 4-ton engine, yada yada yada.

Learn from MCI's experience with 12V71s in their MC6s in Canada. If they couldn't make a success of it . . .

sort of an insane engine to use, so if you have the skills to make it work go for it. Most likely need a roadranger trans or equal, and a rear out of a semi. I have worked with a lot of Detroit"s, have a blower sitting on my work bench waiting for me to rebuild right now. Love the sound, and the reliability.

The NA version of that engine produces nearly 700hp and 1700 ft. lbs. Transmission, driveline, differential... all need to go.

Front suspension would need a full rework to support the weight (~4500 lbs)

Frame would probably need some attention to keep it from twisting up under load.

Basically.. the engine may be cheap... but the swap is going to get VERY costly... VERY quickly.

If I were you... I'd look for other smaller options. May I ask why you want to swap the 8.2 in the first place? Is it a power issue or just lack of competent mechanics in the area?

Considering the 8.2 produces around 400-500 ft. lbs.. You could easily swap in a 5.9 Cummins and make more power for a lot less. Parts are cheap and easy to find (literally every parts store in the country has parts for a 5.9). Its rock solid reliable... and everyone knows how to work on them. They are very easy to come by and easy to make good power with. Not only that, but you could more then likely bolt it up to your current transmission... built some motor mounts and go with it.

ok I know this is a little nuts but....how about doing it as a mid engine set up with a glass(plexiglass) case around the engine, could be the "coffee" table so to speak.

Fitting the engine in the chassis isn't the problem. With a welder and some fab skills... you can basically make anything fit. The problem is making it work well and be useable in the real world. The fuel costs alone would make it not worth the effort. If it's something just to show off from time to time.. maybe worth it. If it's something that will actually be used... nah.

What you had said before is right on in terms of what is most practical, and prudent. And what I would recommend to someone who may not have the most experiance doing a crazy build like this. However for someone with real skills this is a doable project, practical no, fuel efficient no. Can it be done to be reliable yes I think so. I have done a number of projects, and would feel very comfortable building this. I right now am in the idea stage for my bus, it has a 392V-8 international. Call me nuts but I like the old international gas engines have built a few of them. It is temping to do twin turbo with fuel injection on this one. The low compression, forged crank, long skirt block, makes them a good candidate. On the practical side I take cross country trips and need reliablity, as well as something I can get parts for on the road if need be. Build anything to far outside the box and parts become a real problem away from home. So realistically fuel injection and some other minor things, but no turbos might be what I really do.

This fellow needs to be thinking of all these things, and to what purpose the build is for, and what is his skill level? Of course I hope he has what it takes and does it just because it can be done.

As mentioned above, 16v71 is an ENORMOUS engine, any of the old timers know if they even put them in an OTR application? 8v71 is a great bus-size motor, I would want a Tugboat or something for a 16...

I've seen 12v71's in ORT application but never a 16v71.

I imagine one of those swapped into and RE bus looking similar to the VW van with a 350 Chevy in the back. Just a larger scale.....

I'd settle for a 12v!
