I have a BBC Weiand Comp 671 Blower fully built hard case anodized, BDS rotors hard anodized and teflon stripped. fully polished. pro build by Magno Superchargers. Also has fluid eye sight and presure relief valve. Also Weiand fully polished manifold with big burst panel and port injection, and offset plate by BDS for running a 12,14 or 1671 blower on this manifold. never used with 1/8 O-ring and CNC for port injection clearance. and dual carb adaptor. The blower was only ran 2 times for 15 min's. its fresh and tight, all pro built for top alky. the case is and looks alot bigger than any 671 you've seen. will push alot of air with very little over drive. set up for either pump gas or alky. I have several pictures I will send. I tried to down load them on sight but was too big. e-mail me back @ jimmydprince@yahoo.com or call 818-807-2219. or come see you'll be impressed. Thanks. Boat people get a deal.
