Did they happen to give a price?  I didn't listen to the whole video.

No...... I think it's one of those "if you have to ask you can't afford it" deals!

It's interesting that it was designed to take either the BMW 4 valve motorcycle head or the 12G940

The space between #2 & #3 where the headgasket would go looked razor thin to me......

Of course, you also need the crank and connecting rods for the 5 main crank setup.

They talked about up to 600 HP and 10K+ RPM! And of course there are NO mini transmissions capable of handling that sort of power.....so I guess that's next?

It's a little hard to tell but it did not look like it had been sleeved yet so perhaps that will thicken up a bit depending on how they go about that part of it, either a traditional sleeve or the newer plasma sprayed coatings some use.

10,000 RPM!  Wow.   

They didn't really talk capacity either.  I wonder what size the prototypes will be built as?

Stock 1275 + 40 over is what I'm reading.

Early engines "only" 350 hp!

If you scroll down their Facebook page they have an interesting take on the 5 main crank, using a tapered and splined end for the flywheel, and a pressure fed thrust washer on the rear main instead of the center mains. They also have  a unique design for the con rods that they claim are in fact good for 10K RPM and 350 hp.

Oh, and the main caps are 4 bolt.

All the stuff Honda and Chevy already do.....
