Hot Rods THE INDUCTION THREAD

First design Say-Why-And I believe it's in my '69 catalog. I've never understood why so many supposedly period cars are running tunnel rams and aluminum slots when they didn't come out till 1969
The Big Block first design Say-Why-And tunnel ram was similar in the center and was actually 3 pieces. The top was 2 pieces. There is no Hi-Ram (tunnel ram) in the 1968 Weiand catalog.
