W2 Blower Manifolds?

If you coulld find a manifold for standard 340 heads, it could be modified rather easily for the W-2's. A little welding and grinding.

Dick Landy's got 'em for 318-360 LA and even magnum motors. http://www.dicklandy.com/Products/index.htm#Supercharger I thought that the intake bolt pattern was way different for the W2's? I don't have a TIG welder......Yet, lol. Oval vs. Rectangular would be a challenge too and I'm thinking that without a purpose made manifold, there would be no point in spending the money on the heads.

Edit: Holy Smokes! I just re-read that catalog and they got 'em for W2/W5 heads!

So what say y'all? 10 psi? 650 hp@6200 rpm? Pipe dream or reality? Will I need a radiator as big the windshield? A bigger cam? Will I have to stroke it to pull this off? I'd rather not for longevities sake and keep the piston speed low.
