Blower pulleys configuration?

Hello everyone!
I have a 78 vette with a basic stock/cast 350. Recently I obtained a weiand 6-71 blower w/ 2-600 holleys. My question is can I run this blower underdriven at just 5-7 lbs? My mechanic is a forced induction freak. He assures me that i'll be ok with running the blower on my current engine as long as i dont get "foolish" with it. So my question to you all is what blower pulleys do I need to run to reach my target boost of 5-7lbs?
The blower came with a 39-cog upper pulley and a 31-cog lower. The person I purchased this from advised me that pulley configuration is what Im looking for, just need some confirmation from you guys first please.
Any help is greatly appreciated!
