Packard Forum Index » Pre-War (1899-1942)

Couldn't upload as document, only as download. You can see the two hands in the picture. Usually set my second indicator at 3,000 in my 120, reasoning that was high as i took it as a rule, good for 90 in OD, not that i drove it that fast. (The period 4,500-rpm steering column mounted Stewart-Warner tach driving off the distributor in my '47 Super Clipper is set at 2,500 (75 mph in OD).)

The standard tach in 1936-37 Cords, like the 1939 Packard accessory tach, reads to 5,000 rpm. But that's slightly more rational, since the Cord's 288-ci Lycoming V-8 had a relatively short 3 3/4" stroke; same bore/stroke as 1948-54 Packard inline 288, and those latter underrated engines would wind.
