Is the 327 out of a passenger car or out of a truck? That will make a big difference in terms of power. See if it has a "High Perf" stamp on it. If it does, I'd go with that over a truck 350. That only applies if the 350 isn't stamped "High Perf," then I'd go with that one. In an old truck, cubes are your friend. To get one of these old bricks moving, you need low end (which you won't find much of in a 302, but the 350 should be plenty). Go as big as you can IMO, providing they're all equally built.
