There's a bunch of BBs running with stock hoods. You may need to modify the engine mounts on the frame. Typically, the frames are built with BB or SB in mind.

You might need to worry about the trannie too. For example, a T-5 won't handle BB torque for very long.

I'm not familiar with the Shell Valley chassis, and I don't know anyone with one, but that doesn't mean it hasn't been done.
