the basic engine block is the same, depending on the year and if car or truck as to how it is equiped internaly and also the accessory brackets are diffrent also. it all depends on the years and what car it came out of. basicaly a 460 is a 460 unless you get one from a car older than 1973. also the newer ones after about 1978 were externally balenced.
the older car engines have higher compression pistons and heads. the newer ones have dished pistons low comp. heads and are more likely to have a rear sump oil pan.
it really all depends on what you are doing with it as to wich one or year you need. the old ones if you can afford to pour good gas in them make more power.
to really answer your question good I would need more info.
I hope this is a help and that someone else will add to it as I didn't list all the diffrences there are between them.

Well what I was looking to do is pull the 351M from my 1979 F250 and replace it with a 460. The truck has a C6 trans. Hoping to find a cheap full size car with this engine so I can do the swap.
Maybe use the Edit Button?
Car 460's have more emissions equipment !

the problem is the mounts for the engine are diffrent. you will have to buy or build to bolt the engine to the truck. on my truck I have a piece of 3/4" steel pads that have two holes in it with bolts going into the engine block and one threaded hole in the plate for a bolt to screw in from the bottom to hold the engine in place, or if you like to spend Money there are a few places that make custom mounts. L&L is one of them.
EDIT: (the above aplies to a orignaly FE powered 4x4) your engine frame mounts may be diffrent.
yes a 460 will bolt right up to your C6 where your 351m was.
also you will need a "truck" exaust manifold for the passenger side unless you want to trim the top edge of the frame rail, the car manifolds will work if you do this but if you ever decide to go to a standerd trans the exaust pipe won't fit past the clutch housing and starter if you use a car exaust manifold. the drivers side is not a problem car or truck will work, or you could just buy a set of headers.
other than that its pretty easy, hookup all the little things and walla you have a 460
