Which Whipple would be best for 632 CUIN Chevy

Hi - could somebody recomend the best Whipple for a 632 cuin bbc?

I'm guessing that W305ax and W510ax are the most likely candidates
or could you suggest a more appropriate one?
They both seem to peak at 3462 cfm, so which would be the best?
Obviously the W305AX would need more overdrive to provide the same
boost as the W510AX - is it more efficient to use a bigger blower
at low overdrive, or a small blower at higher overdrive?

Any idea of what sort of boost could I expect from the above blowers
feeding a 632? (Big Chief heads, ex Pro Mod engine).

My application is for a drag racer that has to be run on the street
occassionally to qualify as a road going vehicle. Performance will
have to be in the 7.5 second, 190+ MPH to be competitive.

Limey,
Your best bet would be to call in and talk to Dustin. The W305 and W510 are his expertise. He is at SEMA right now and will return Friday, 11/6/09. HE will have some questions for you on the motor and will be able to help you with what power to expect, what boost to run and so on for your needs.
