Sixpack on a 318 engine ?

Back when mopar did the last 6pack repop for restoration parts I thought the price was stupid, I can’t exactly remember what what it was, but I thought it was way too much. Oh boy was I wrong, I should have bought a dozen of them.
If I could go back 35 years I'd buy and invest in a lot of things that are worth a fortune today, I remember when I could of bought a fully restored T/A Challenger for $25,000 and thought it was crazy money and $50,000 Hemi cars.
