There's a great tech article in the current (January 2009) issue of Classic Motorsports called "Scientific Method" by Per Schroeder. The subject of the article is one of the quickest vintage Formula Fords on the east coast: The SascoSports Lola 200. The idea of the article is how to use current technology to increase the performance of vintage racecars. A lot of good ideas and information here. The dyno and data charts are very informative.
