"Fit" is a relative term, how much work do you want to do. There is a 8V92TA powered FC running around somewhere, and a 3406 powered, you can make space if you want to exceed 400hp.
For my money, I would take the path of least resistance: a reman Cat 3208Ta/250hp.
It isn't the most modern engine, and better alternatives are out there, but the engine will fit everything from the engine mounts and transmission to the pumps & brackets with minor doghouse modification for the turbo) and this saves a pile of searching, buying, and modifying.
Your '77 FC33 with a 250hp 3208 and 4.44:1 gears will run 75+ miles per hour, tow and climb more strongly than your current engine with less smoke, and the fuel mileage should improve with the gear ratio change. You're only 26,000lbs and should be able to run with my 300hp/33,000lb '88FC which runs 75 on the cruise, much happier there than my re-geared '77 (which also ran 75 on the cruise). The transmission is rated for the power, the radiator or fan might need improvement however.
There is a '77 FC31 at Holland Motorhomes / Holland Bus Company in Holland getting a 250hp reman and re-ratio, they should be able to give you a very close estimate in the next week or so. It won't be cheap, new engines never are. Mike Hohnstein in Wisconsin just finished installing a reman 250hp in his '83 also, might be a good source for information.
