Flat plane crank

Might be able to put a flat crank in a 340 block. The stroke would have to be really short so you might only end up with 300 inches or so but it would scream. Might want to use a 48 degree block so the valvetrain would work better. Put some good heads on it, maybe W9 or the new Edelbrock heads. Probably cost $30K or more to build but it would sound killer. Definitely would get some attention.
