Going Faster in 1954

I have a large library in my office consisting of Hot Rod How-to books and annuals from the 1940s, ‘50s and ‘60s. During one of my recent review sessions I found a chapter introducing nitromethane and its use for drag racing. Keep in mind this is 1954 technology… The article began by explaining that hot rodders
