174/177 supercharged small block, where to start?

The Blower Shop, has a complete 174 kit for a bb chevy listed under their used section for 1500. They are 5 hours from you. Buy it without the manifold or with the manifold and sell the manifold on Ebag.
They might be able to make an adaptor plate for the Mod Man Manifold and adapt the chevy crank pulley to mate up to a Mopar.
I bought an all billet 8-71 from them and am happy with their products and customer service.
