Which was more or less a NASCAR power rating in 1968, wasn't it?
NASCAR Ford engines were in the 500's then SAE short track 530 and Daytona in the 560-580 range according to Mose Knowland who was a key engine guy with Ford then. He showed me some of the dyno runs from that era and the highest power levels were dual four barrel engines.
