Incredible, I love seeing machining stuff like this, it's amazing what you can do with the willingness to attack the hurdles. How does the firing order get changed with the crank design now? IIRC an inline 6 or V12 is very well balanced harmonically due to evenly spaced firing pulses, are you getting the same effect using this arrangement as opposed to an engine designed from the outset to be a 12 cyl?
Most of the cylinders are on 45 degree centers, with four cylinders on 90 degree centers. The crank has the inverse firing order on each side, front to back/back to front.
We are utilizing a 90 degree block instead of a 60 degree block. This is the only other practical solution other than an even fire crank. It should be a wicked sounding V12 that's really a cross between a v16 and a v8

Awesome. The same kind of stuff Ryan Falconer was doing to 400"SBC back in the 1990s. I think he has his own block and 32 valve heads castings now I think.
This plus a pair of turbos in a 1500 4X4 truck please!!!
