Ps, mechanical tach cable drives are race car applications and I believe MAYBE some later 50-early 60s street car / off road / marine applications used a cable driven tach
My 64 300 had a mechanical tach drive distributor. Had the 360hp 413 in it, not the 390hp version. No tach though, so I suspect it was simple a matter of all dual points had a mechanical tach drive by that point? Another possibility was that in the 24 years from the time it was built till I bought it someone swapped it in, lol.
