833 OD behind a 340?

I plan on putting the 340 from my Duster into my 67 Barracuda, and am wanting to put a manual trans in there instead of an auto. From the dyno, I calculated the engine made about 330 hp. Would an aluminum case over drive 833 hold up behind this or should I look for a standard 4 speed? A 5 speed conversion probably won't happen. Having the OD would be nice, but isn't necessary.
