factory tachs

[tjakups]

Does anyone know of any documentation for factory tachs for '63 Chevys. I have always assumed the small blocks got 6k tachs and the 409s got 7k tachs. Any info would be appreciated. Thanks

The 340 horse 409 got a 6K tach, also. The HP 409s got the 7K tachs.

Solid lifter cars got the 7K tachs and the hydraulic lifter cars got the 6K tachs.
