Kent,
That is Willard Havens old car (I believe Bob Macy bought it... from Texas?). It was featured in the NCOA magazine, but I cant remember which issue. Willard is a member of our club (Maryland Chevelle Club). EMail me offline with your number and I'll call Willard and get you guys together. He can tell you anything about that engine that you want to know.
