Well, there are allot of things that are different in for example the 660 Raptor and the 660 Grizz. The auto trans is good for about a 20% power drop over the Gear on gear manual trans. The weight is also a significant power damper but more important the unsprung weight of the wheels and tires used on the machines. The Grizz uses a much larger and heavy 25" tire. There are allot of fokes that compound that issue by adding even larger heavy sidewall mud tires. Stock tires on a utility vs heavy mud tires on a utility can drop a 4x4 as much as 10 to 15% of power between the 2. Shaft vs chain drives also are a cause of power loss and 4x4's have the added drag of the front drive system.

No, not at all you still have shafts and 2 of them at that. The other problem is the gearing or pulleys if you will are all wrong for 20" tires Your kodiak would likely loose a great deal of performance by going to 20" tires. I tried some paddels I had left over from my v-force on a prairie of mine it ran better with nobby's than the short 22" paddels. I now run some very light 25" paddels that has made a word of difference.

I don't know of any direct crossover engines. I think the raptor/grizzly and the KFX700/P700 are close but there are a lot of differences. Even if the engines were the same mechinically they would tune the Ute for more bottom end with ignition mapping and exhaust set ups.
