67 Cuda 273 replacement options

I'm running the original 273 in my 1967 Barracuda "S" Convertible. When I rebuilt it (after 232,000 miles) I had to bore it .020 and swapped in a Comp Cams bumpstick that was just a tad hotter than the original. The machine work was top notch and after new pistons, cam, bearings, gaskets, etc I probably have about $3,000 in it. It runs great, has all the power I want and still idles smooth for the occasional parade.
