Born and raised near Falmouth, Kentucky, and a graduate of Pendleton County High School, Alan has been active in the old car hobby since 1975, when he purchased his first car, a 1957 Chevy. Later on, he owned a nationally known Chevrolet reproduction parts company that supplied many detailed reproduction parts to the old car hobby, one of which was the first stainless steel chambered exhaust system for Camaros. His involvement in this business has given him invaluable hands on experience in parts manufacturing in the restoration field.

His greatest achievement to date has been the publishing of his landmark 4-book series “Chevrolet by the Numbers” which is the only authoritative reference for identifying the correct Chevrolet drivetrain parts for your vehicle. These books were the first books published outside of General Motors to carry a GM part number and have been sold worldwide through the General Motors parts system. His last book in the series, Corvette by the Numbers, was published in the spring of 2002. In 2000, he won a Gold and a Silver Medal for two articles submitted to the International Automotive Media (IAMA) Conference.
