Just to pass on to those who are enjoying this thread. Just got a new book, "Maximum Performance- Mopar Super Stock Drag Racing, 1962-1969" by Jim Schild. Have not finished reading it yet, but it is great! In great detail, traces Mopar high performance from the beginning but focussing on 1960's. Including rule changes and the creating of new classes, how things changed and evolved. Bought this through Summit.
