W2 Blower Manifolds?

i have read somewhere about some australian company making blower manifolds for W2 smallblocks ;)
btw i have also started on one of these stupid blower smallblockbuilds, mostly planing so far but i already have a lysholm screwtype blower and am planing to have an old aluminum intake manifold rearanged to work with that blower and then a big fat dominator on top of it all, will run my old eddyheads and yes im planing on somewhere north of 600hp anyone want to gues how much power a solidrollercamed eddyheaded pumpgas 340 can make runing some 14psi of boost ? my plan is also that Every Hondaccurazukiotabmvolvoararri in the hood will freak ;)
