Reegs Posted September 1, 2016 Posted September 1, 2016 (edited) The mid-60s NHRA rules stipulate: G/Gas and H/Gas were for non-supercharged pre-1960 flathead V-8’s, in-line six cylinder and straight eight engines with stock production-type heads and pre-1960 unblown 4-cylinders with any type head.To me it could be read two different ways.Did it mean V-8s but only if pre-1960 flathead, OR any type (OHV or flathead) inline 6 or straight 8?Or did it mean only pre-1960 flathead engines: V-8 flathead, inline 6 flathead, or straight 8 flathead?

dragcarz Posted September 1, 2016 Posted September 1, 2016 My interpatation is the first. Pre 60 Flat head V8, any 6 cylinder, or Straight 8 .
Ace-Garageguy Posted September 2, 2016 Posted September 2, 2016 And...the reason it stipulates "any type head" for the old 4-cylinder engines is because there was an almost unbelievably wide array of trick heads for Model T and A (and their derivatives) engines...including DOHC. The little engines were allowed to run the exotic heads to make them more competitive, naturally.
