In John Wipff's 'The Compleat History of the Corvair" Vol.#1 there's an article on this engine on page# 113. It was written by Ronald W. Nordquist of Aurora CO. He goes on and tells how he got one of these engines and installed it in his '65 Corsa. Lot's of good pictures and an interesting article.
