I guess if you are keeping it you can do whatever you want -- but I'd never put a carb'd engine in a modern v-drive. If I were you, I'd build a marine LS. You can find a cheap junkyard pull, install a marine cam and all of the marine accessories and get into it pretty cheap. There's also TONS of after market electronics/parts/accessories/etc. I'm not sure where you'd find a trans and v-drive but the LS should be easy to mate up to whatever you find.
