1970's book about nascar question  

Does anybody remember a book from the mid 70's that had chapter's about Tiny Lund, Walter Ballard, and a very early interview with Dale Earnhardt, before he was in winston cup? I used to have it but loaned it to someone years ago and never got it back. I don't remember the title. (I should get Mr. Bookman the library cop on the case.) 😁 Thanks in advance.
