How about this manifold on a b2k?

You could rev to the limit of turbos or motor with this thing. Discuss.....

I believe it is from one of the GS 80's - Jim Jones who has been buiding engines for Callaway Cars as of recent used to own Traco and built those cars - He might have more info on that intake - My guess is, it dosen't have tremendous volume but would allow for many revs
