Reading through the threads this weekend I think I may go this direction. Build a stock stroke 273 next year, similar to TMM, and enjoy that till I can get enough money, parts, and time to build one of the other engines I want to build. I was thinking about making an engine run-in stand/fixture in the future to test a swap before I put it in. Then when I do my engine swap, I take my 273 and trans out and I can put it in a early-A.
