I got one heck of a laugh years ago (1980's). While I was laid off from the steel mill I picked up a job at a local transmission shop pulling and replacing transmissions to stay out of the bars every night. This place was owned and operated by several dirt track racers so "dirt track" books were laying around. I picked one up and it was discussing camshafts and how they work. Towards the end of the article it touched on drag racing. The author wrote " I don't know how these drag racing machines even start with these BIG, sometimes up to .750 lift even start. LOL. Boy he should see what we are running now.
