On eBay. And it's a Burgundy Mist car. https://www.ebay.com/itm/1970-Buick...rentrq:d910486716d0aad3077ad7bafff8147f|iid:1
If the winning bid was $23K it looks like they got a great deal. But a Window Rattler in a car with power brakes and auto trans? Kenne Bell said that would be a bad combo, due to the high idle and low vacuum characteristics of the cam. I put one in my car's engine, but it has a Muncie and no options.
It's back. https://www.ebay.com/itm/1970-Buick-GS-455/163913791392?hash=item262a05f7a0:g:ZRIAAOSwIJZdm~HO
