1965 NHRA Rule Book Page 15 - Gas & Supercharged Gas Coupes/Sedans Classes

This is page 15 of what is identified as the 1965 NHRA (National Hot Rod Association) drag racing rule book. The page defines class structures for two competition divisions. Section A covers the Gas Coupes/Sedans Division (G), which contains eight classes for non-supercharged cars; class placement is determined by total car weight divided by total engine displacement in cubic inches. Classes A/G through F/G span from 5.00 lbs. per cubic inch up to 14.60 or more lbs. per cubic inch, while classes G/G and H/G are reserved for non-supercharged pre-1960 flathead V-8s, in-line six-cylinder, and straight-eight engines with stock production-type heads. Section B covers the Supercharged Gas Coupes/Sedans Division (GS), with three classes (A/GS, B/GS, C/GS) ranging from 6.00 lbs. per cubic inch to 12.00 or more, and notes that class requirements match those outlined for all cars in the Street Section. Two period photographs illustrate the page: a coupe numbered 290 C/GAS and a supercharged Willys gasser numbered 539 A/GS lettered "Stone Woods & Cookie." This page is a historical reference for vintage drag racing classification, not a vehicle service document.
