Sorry, but I got to go with keeping the cars as they were originally run . With a stick! Plus allowing Data recorders? No such device in the 70's. I loved watching the old Pro Stocks and have a few pictures of those cars in the 70's when I visisted Englishtown back then. Every year we have 2 nostaligia days at LVD and my favorite cars are always the stick shifted cars. To those that can't tell the difference of a 4 speed vs. glide, just look at the shifter!
