I do have A 6-71 blower Handy, and I think I'll try to use that. I'll probally have to mess with pullys to get the right ratio.
Here's how the thread is going elsewhere:

"There is a guy on the H.A.M.B site running an 8-71 on his 270 six, and he says it can keep up with the stupid little ricers on the highway, so I was thinking my 6-71 would probably work fine.
I'm not looking for a full out race motor, but I want to be able to show those ricers what a real hot rod looks and sounds like
If I get 350HP and 350ft.lbs I'd be happy, It'll top at about 10psi boost and 6000 RPM, and It's going to be a daily driver anyway...

Hank, Or somebody, Could you please suggest some cam specs for me?

That'll have me running a Holley 600 (http://holley.com/0-80592S.asp), Clifford intake, lump ports, 1.94I/1.50E valves, Long tube headers, Ross Pistons, and the 6-71 Blower. "
