I wonder if Jay has considered a flat-plane stroker crank? The vid below is long but it well explains the benefits and detriments of a flat plane crank. Seeing the huge FE stroker crank, I wonder how much lighter it would be as a flat crank. Given the benefits of the SOHC heads and high rpm potential, I wonder how much more hp could be achieved?

Interesting, but flat plane 90 degree V-8's trade a bit more horsepower for A LOT more imbalance (especially for big displacement mills like this one).  I'd be afraid of breaking the block at high rpm just from the inertia loads.

You also have to make a pair of custom SOHC cams to work with the new firing order.  Admittedly, the thing would sound awesome!
A careful study of failure will yield the ingredients for success.
