The people that have build these engine are not able to get it on the market. They can build one-off engines but not production. If you were really wanting to do something like this get with them and see what is required to get the engine that already exist into production.
For some reason these links are not working, see post #15. The last link is a very detailed video.

I would love to see one on the market, but just don't believe it is going to happen anytime soon. The Motor City block has been advertised as ready to be mass produced for years. "Ready this fall" "Early next year" etc. for years!
