Best 273 and 318 builds (NO 360's please)

I forgot to mention that I do have some personal experience with modded 318's. Before my duster got it's 360, I ran a 318 with a m/p cam, gear drive, eddy manifold, holley 600, and a set of 302's milled and fitted with 2.02/1.60 valves. It was a blast! (until it blew up!) It was so much fun that it made me rethink 318's.
