The Amoco 93 had a very distinctive exhaust smell, & so does the Avgas. I'm guessing the American White 93 became Amoco later.

Great, muscle cars where a lot of fun. American White was the best, but it is no longer the same because all fuels are now unleaded. The aviation fuel was fantastic add to the mixture, but you still destroy an engine if you weren't careful. Chevy man here. Owned a 55, 56, 57, 58. A 67, 68, 69 Camaro's. My new one off the lot in 64 was a Chevelle, built in June as a half year version. Had a 327, 300hp vette engine, Munice close ratio 4 speed and positraction. I changed the side flags to the 283 flags. So now I had a sleeper. Had a buddy with 64 Plymouth Valiant, 2 door and was the cheapest body style made. But, it had a V8, 4 speed and positraction too. Another sleeper looking for a pray.
