My dad was an engine tech at an engine rebuilding, and dyno shop in the sixties. Carroll Shelby was in the market to buy a farm in our district. I surmise Carroll shared info about Ford's brand new Challenger V-8 and it's race versions with my dad. My dad passed away in 2000, so I inherited my dad's paperwork. I compiled this cart from various sources. A young guy asked a question about the 255 Indy engine, I tried to contact him, but his e-mail was fake. Hopefully he will see this post, if not you fordanatics out there can enjoy it. drop that clutch!!

 

Like to have a few of those...

 

Yeah, cute little guys. Only flaw they had was the small bore diameter. In normally aspirated form this restricted valve size and ultimate power. There are a few hiding on shelve around the U.S. on shelves. When the owners pass away, I hope relatives don't scrap them - ouch!
