The 1650 has a shorter engine bay. The hood won't fit and you wouldn't be able to use the front PTO for a mower.
Now the other end is a little better. I'm not sure, but I think some of the early 1650's had Sundstrand hydros like the 1655, and I'm fairly sure that the guts of the rear ends are the same even if the 1650 has an Eaton. The rear axles and axle trumpets should be a direct swap. If the 1650 has an Eaton and you're parting out the 1655, swap the hydro and rear end into the 1650. You have an option for the rear axles, but the rims are specific to the axles, 6 bolt on the 1655 and 5 bolt on the 1650.
The hydraulic components are always nice to have around. You have some nice options there, as well.

That's why I suggested finding an engine for the 1655. There is an Onan for sale in KY on the other forum. He wants $450 and there is no flywheel. I believe that it's a P220. I'd either try fitting the Kohler in there or do a complete refurb on it while looking for an Onan. Fitting the Kohler will take measuring, measuring, measuring, and then measure it again. Plus making a new drive shaft for the lower crank. If I recall correctly, Olcowhand and others have mentioned that the drive shaft in the 1650 should have universals. Alignment could be tricky without them in the 1655. The engine cradle in the 1655 may need an adapter plate to accommodate the Kohler base bolts, or the engine cradle from the 1650 may drop right in, if there is one. For sure throttle and choke cables will have to be rerouted and a bit of wireing.
The flywheel stub shafts are different, but a new one can be easily made at a machine shop using 1" superior ground shafting and a new base plate. I did that with mine to cut down on operating expenses. I used to strip the splines out of one pulley every 6 months until I changed all my drives to the shafting. That made it easy for universals and industrial cast iron pulleys, but you still need a splined coupler for the hydro.
My best advice is to be patient and think about what you want to do. There are many options and you really don't want to close any doors before you have explored them. Onans are in many tractors, from Sears Suburban to Case to John Deere. You may luck out on acquireing an engine from an otherwise derelict tractor or from someone who just wanted a new mower.
That 1655 is an awesome piece of machinery, once it's running. It took me 5 years to get mine from when I saw my first one on the showroom floor on 1977. I still have it, and my 8 month old grandson will inherit it when I'm gone.
