The 460 is supposed to be the easiest to make work, but all of them will take some serious mods to work RIGHT.
Can't just throw the cylinder on and expect performance - besides welding and drilling the bottom end you need to degree the engine and calculate proper base height for correct port timing, match the transfers, etc. Depending on top end you may also need to trim the bottom of the cylinder and run a stroker crank. I have seen videos of improperly assembled homemade franks that run and sound great but are only doing ~35mph...thats a stock chinagirl speed. A true frank setup should do 60+ pretty easily.
A lot of work though lol.
