Tom,
I like your Yenko story. I had a similar problem with my 69 Hurst/Olds at a show last year. The guy classing the cars put me in with the 442s. I told him that a H/O was NOT a 442, and that I should be properly placed in another class. He decided to show me how much he knew and looked square at the mailbox on the hood and said "Listen, if you've got that 442 cubic inch engine, you are a 442. It says so right on your hood!"
I threw it in reverse and went home. I couldn't argue with logic like that! I am just glad he didn't see any correlation between the "HO" on the hood and my girlfriend in the pasenger seat !
