Correction - apparently this is for a B&M supercharger, not a 6-71 as stated in the title. I bought this with the intention of using this intake plus an adaptor for a 4-71 onto a sbc but have since changed my mind. Intake is obviously used but I see no evidence of abuse. $200 OBO plus shipping.
A member pointed out the elongated mount holes for the center ports of the heads, like it was modified for Vortex heads. Take a look at the pics.
