Eric,
Sorry to hear of your mis-fortune with that cracked block!
Sure wish you were closer. I've got a spare 235 sitting in the garage, looking to be used.
You'll probably be able to find something out there. I went through the same experience with my 46. Found a guy nearby that was "rodding" a 39 coupe. Bought his fully rebuilt entire drive-train for $250. Good Luck with the search.
