George, I don't think you can get a "smooth" firing order using the V8 90 degree crank. Depending on how you set up the valve timing, a 720 degree firing cycle would go 180-90-180-270 or 180-270-180-90. You can't get 180 degrees of crankshaft rotation between each of the 4 cylinders in the firing cycle. Seems to me the engine would run ruff.
