Can it be done? Yes.
Can you do it? Unknown.
How many miles and what is the condition of the engine? Have you done a compression test?
There is no point in adding a turbo or anything else to a worn out engine.
What vehicle, transmission, axle ratio and tire are you running? A different "adjustment" may suit your needs.

There is a certification label on the door jamb with an axle code. There is (was?) a tag on the axle on one of the bolts holding the rear cover on. Either the code or all the numbers from the tag will tell what your ratio is.
What is the problem with it?
--slow acceleration? Maybe too tall of an axle ratio, or bigger tires. Like a 3.54 axle with 40" tires.
--low top speed, screaming on the freeway? Too short of an axle ratio, something like 4.88s with standard tires.
--poor fuel economy? Standard on every 460 equipped 3/4 ton truck.....
