Way back in the last century I went to a performance clinic that was hosted by Dick Harell.
It was all about the brand new Thermo Quad. He had his Pro/Stock and Funny car there. I always thought that the plastic center section was a good idea and I felt that they were very good carbs. Although I've never owned one.
You can clearly see 2 of them poking out of the hood of his Camaro in this picture.
