There is not a better looking engine than a fully decked out Buick Nailhead with factory aluminum valve covers and dual quad set up.
Back when I had my 63 Riviera I searched all over for a set of those valve covers and didn't find a set until after I had sold it.
This cool engine is wrapped up in a Wildcat body - style and comfort and performance. Wish I had an empty bay. 1964 Wildcat
