A s1700 straight truck offered a 6v92ta as an optain so I will have to break down the serial numbers in order to fool the parts computer at IH into giving me a part number for the proper radiator. I predict that I will have a custom build for a radiator.
You mention the radiator may need to be changed. Just bear in mind that 2-stroke Detroits produce a lot of heat, much more than similar-capacity 4-strokes. (When Greyhound re-engined some MC9s from 6V92s to Series 50s, they only needed one of the original radiators for the new engine, and the other was used instead for a charge air cooler.) Even front-mounted in a truck or FE bus it will need to deal with up to 12,000 BTU per minute heat rejection. Having just completely replaced my bus's entire cooling system, including having the biggest radiator core made that will fit, I strongly suggest using the biggest and best radiator you can. I now have a 6-row 4"-thick radiator (same as before), but with 27% more tubes and 10% greater surface area, the tubes are now dimpled, and there's a much closer fin spacing. Because there will be more airflow resistance through it than before, I have a high-performance 9-blade fan from Multi-Wing that should draw more air through it than the archaic old 6-blade steel fan. You may want to consider doing something similar.
Is that a rear-mounted alternator or A/C compressor? Is it direct-driven off the blower drive?
I have plenty of options. I could pick up a s2600 hood and radiator housing if I want ShortBus to look meaner but I think a custom radiator that fits the 1700 and 1900s will be a smarter way to go. But still..... a setback front axle on the nose of a bus would look cool. I would just need to add a section of frame to the nose. The front axle remains in the same place even though the 2600 is called a setback fron axle truck. S series cabs are the same. Your big bus has more plumbing to deal with than this little bus. For instance. I wont need a tranny cooler. Shortbus is getting a 7 speed road ranger with a clutch. Peace!
ive never been in a front engine 2 stroke.. I remember riding city busses as a kid that had 2 strokes in the back.. at least im assuming since it sound like they wouldrev to redline before the bus would start to move, then they would shift Hard!!..
I can only imagine running like that for hours down the road in an FE where the engine is under you..

I always did like the grill on these internationals!!!

It's painful, and the idea of traveling hundreds of miles in mine is pretty discouraging. I'll work on sound deadening the doghouse soon...
At this point, @ 55mph... You can't hear an iPhone's loudest alarm 3' away from your head

I love running down the road on my moped, with that two stroke buzzing through the race pipe and panty hose air filter.
Different strokes for different folks!
Still prefer 2 stroke motorcycles over 4 stroke. That "ring-ding" noise is the REAL sound of power. The FIM (European racing body) did a scientific study many years ago to determine how much to handicap the 2 strokes since they had won every GP for nearly 15 years straight. They determined that..."a normally aspirated, gasoline burning 2 cycle engine will produce 40% more horsepower per Cubic Centimeter than a normally aspirated, gasoline burning 4 cycle engine". End of story. My 373 cc, 200 pound homebuilt 2 cycle Yamaha smoked a 125 HP wheel dyno and every 4 stroke I raced against up to and including 1200 cc fire breathers. Ya...it was fun to ride.

I once pulled the transmission out of a Camaro... And for giggles, I started it up.
The up & down throttle response was amazing with no flywheel/torque converter resistance.
My ski boat is like that because of the Hurth Direct Drive Hydraulic Transmission (1 forward gear, 1 reverse gear)
And I always hated the smell of burnt diesel fuel... Till I owned one! Now it smells like roses.

All the DDs used to make that vid used straight pipes. A nice tuned muffler will mellow that sound. Of coarse I will run straight pipes at first or install a cut out so I can scare the crap out of tourists in a beach traffic jam. And smoke em out a bit.. lol
