Now you wouldn't be harboring a sixpack manifold for a Buick would you? I know about 3500 Buick enthusiasts who would be interested in purchasing it!!!
Bill, No I don't have one,but I had a guy tell me they came on early Riviera's fatdaddy Dan, I was sure the dual quad set was for real. Dad's cousin had a '65 Riviera with this set up. fatdaddy
I don't think Buick ever offered a "six-pac" nailhead and they definately didn't come on Rivieras originally. Many aftermarket suppliers, like Edelbrock, offered the pieces to make that set-up. Buick did offer an optional dual quad set-up for nailheads. Here's what one looks like. :TU:
The 64 - 66 Rivs (I don't think it was offered in 63) offered a dual quad setup - nailhead, of course. 425 ci, 360HP
