Here's a few pictures of Jim Amrhein's Team Fercockta roadster from about 1972. I believe it was then running as an F/Fuel Roadster with a Slant-6 with no butterflies in the injectors and held the record as such. It's way modern for its time. It's still in the record book, thirty-six years later, holding the D/Blown Fuel Roadster record at El Mirage, set in 1975, at a respectable 223.
Let's see if I can post a picture with this . . .
