I just bought this book on eBay and I saw there is another one is still listed:

It covers a lot of performance upgrade available for MEL at the time. For instance, it mentioned a stroker kit was available to increase the displacement to 504. Also mentioned: Paxton and Latham provided a bolt-on supercharger kit for MEL. A few 4x2 and 3x2 intakes are also shown. An interseting story about Holman and Moody is featured as well.
