Hey SFD, you could use the 340 from the AMT Duster kit. Just change the carb to a 2 bbl and find a correct air cleaner. Not much difference in the rest of the engine from a 273. The 318 for 65 would have been the old polyspherical head engine. Good luck with that one.
You are right to some extent Bill, but I have no idea who John Galt is. I just bought this issue of ET this morning at the local Wallyworld. ET and Hot Rod Deluxe are the only car rags that I still buy.
