maybe I don't understand but if the engine faces frontwards you don't need drive shafts, are you afraid not to have enough weight in the back?

Look at what trophy trucks are using.... theres a lot of angle and a lot of abuse, 1000 hp and a 38-40" bfg project tire and beadlock rim is 100 lbs easy

Poor man's coating to injector line special fittings. Phosphating process in the easiest way. After acid they bath in alkaline detergent to neutralize and then one hour in motor oil so they suck oil in coating cellular. Time will tell if they not get rust.

Scania 4 series thermostat housings have full internal flow when thermostats are closed, I think it's most important thing in marine engine cooling, no hot spots. Bottom flaps close bybass flow when thermostat opens and force all coolant to heat exchanger. Dual thermostat have few degree difference in opening temperature. Transmash will get own housing to each bank so right and left banks run in same stable temperature. Bigger ports are 60mm diameter so they have quite good flow.

I found old video where we start Transmash alive. It's very rpm sensitive engine unlike conventional big diesels. It run good without flywheel, I won't add any weight to it except transmission internal inertia.

Cooling system update. Threaded freeze plugs give great opportunity change coolant flow from longitudinal to transverse.
Flow route goes:
- pump
-exhaust manifolds
-heads
-cylinder blocks
-thermostat housing
-heat exchanger
-pump again
so flow is opposite as normal, coolest fluid see hottest place first. Exhaust ports and injector area get much better cooling and cylinder liners doesn't run too cold. Too cold liners cause seizing. Cummins guys should think same kind of cooling system on higher HP levels.....

Original freeze plugs get machined holes and o ringed connectors fit heads and manifolds together. I have to make special tool so fittings can screw in place.

You can see very dirty exaust ports, these engines have moderate oil consumption that must solve somehow. Better oil drain from heads and vacuum pump is first steps, if they don't help enough, better oil rings are in shopping cart. Controlled exhaust back pressure in idle may help also, but it kill idle sound....
