Bottom line is that all of us would like to be able to go out and buy new parts like this but how many of us actually would is the mystery.

Here is a post that I previously made on the Kirby project, while impressive I think it's need for many proprietary parts makes it a loser, and doubtful that it will ever be seen in production.
I think the video shows why the project was aborted. In addition to Mark Kirby there was an additional brain trust involved in the project and they re-engineered the whole package. There isn't much they left on the table that is not unique to the MCFH aluminum block; d-ports, smaller, relocated head studs, roller cam and unique guides, proprietary heads needed for new stud locations, revised oil pan, water pumps, front cover, cam gears, Fluiddamper balancer and on and on.
It is for certain a complete work of engineering excellence, but all the upgrades made it out of reach ($$$$$) for the typical hobbiest and it's for that reason I think the project was shelved. Who wouldn't want one, but how many could pay for, or justify the cost?
