Hi Randy;First, I don't have a block for you, but there are a couple on Ebay and some complete motors too. It depends on where you live as to whether it would be cost effective to get one. If I couldn't/wouldn't drive to get it, I would pass on it.
Also, if you are going to go the 292 route instead of the 312 route, I would suggest the C2AE 292 "truck" block. A good, strong block to start your build from.
Good Luck,
Rono
