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

Well, I've got a spare '68 273 block, spare connecting rods from my 360, my old 360 crank, crate engine 360 heads with 1.88" intake valves, a Mopar M1 intake, a Paxton supercharger, and a stock carb-to-pan 273 when my Dart is done. I've thought about building an engine for a pick-up or a wagon. Stroking a 273 would be strange and might provide costly difficulties (machining the crank, clearing the bores, custom pistons, etc.). But the heads with a dual-plane intake and Paxton should make for a fun setup.
