For crying out loud, you don't want a 460 unless you plan on building some sort of 600-plus-horsepower (NA) super-stomper. It weighs over 700 pounds and nothing bolts up without modification. A stock-block 351 is fine for 400hp or more, which is all you can really make use of on the street.
Assuming you'll be building up the whole motor, a 351 won't cost that much more than a 302. With a pre-'94 block there will be a little more expense involved if you want to run a roller cam, and there are some concerns if you want it to be fuel-injected, but that's most of the concerns other than the 100-200 pounds extra weight. Later factory 5.0 cylinder heads (the "GT40" and "GT40-P") come already drilled for 1/2" head bolts, too. A 4-barrel carbureted 351 can be cheap, powerful, reliable, and easy to build.
Throwing the usual HO upgrade parts at your current (injected?) 5.0 will probably be by far the cheapest and easiest, and it'll give you a nice power boost. Heck, I've ended up putting low-mile rebuilt 302s in two different cars that came with 351s just because they're danged convenient, albeit these cars have used AFB carburetion instead of fuel injection. For a some more oomph than the regular HO build, Thumper Performance in Florida sells nice ported heads for under a grand shipped.
