Converting a Cross-Plane V8 to Flat-Plane 1

[theonlynamenottaken]

I'm looking in to converting a cross-plane V8 to a flat-plane. Specifically, the Toyota/Lexus 1UZ. I understand the basics of difference between the two configurations but was looking for recommendations on engineering the balance shaft(s).

I have the CAD/CAM, engineering and machining/welding capabilities but need to figure out those balance shafts. Anyone know of any texts that cover the secondary vibration characteristics of flat-plane V8's? Or perhaps someone knows the specs on the bottom end of Lotus' Espirit, Ferrari's Modena or the TVRs?

I've got a couple of friends that can handle the ECU, ignition and fuel injection but would cherish any advice you folks may have....

i dont know if your still into this, but i have been looking like crazy for and been researching flat plane V8's. and no, the sound can not be produced any other way, except with a quad rotor wankle.
It probably would be easier and cheaper to find a engine that is already made that way, but if you want to convert and need balance shaft calculations, this site is for you:

you may have to do some modifications to the formula, because it is for v-twins, but the shafts will act the same. they will have to be proportionate to the weight, sit opposite to each other one the same plane as the crank, and spin in the opposite direction twice as fast as the crank. its pretty simple once you see it in action. the moto guzzi is the one that has a flat plane design.
