Blown Nailhead with Hilborn EFI - Ever seen it?

I'm working with my engine guy to build a blown 401 Buick nailhead with Hilborn EFI. We have a pretty good idea how to do it, but I was wondering if any of you have ever seen or pulled off such a feat.

The plan is to use an 8-stack Hilborn mechanical injector on top of a custom plenum as the throttle body, and a custom lower manifold with electronic fuel injectors controlled by a F.A.S.T. ECU.

I was just curious if any of you have seen such a thing, or have any input on the subject.
