No brainer-SM 465. Bolts to the stock 327 bell and has the thinest adapter plate available giving you the longest rear driveshaft. An SM420 would also work but parts are getting a little tougher to find, there is more of a front driveshaft clearence problem, and the adapters are longer-it is somewhat lighter. Check Novak's site for the various options. You will have to modify both driveshafts, floor pan/transmission cover, and the cross member but lots of threads on that in several forums.
