A 340 Tach question....

hi dave...
funny that you should mention that problem of factory tachs being slow... now that my memory is jogged a bit... my original 68 fastback s (the one in my avatar) had a factory tach in it but it wasn't very good. so i did what most of the street racers were doing in 1970, i bought a big chrome "Sun Super" tach and strapped it to the stearing column with a screw hose clamp. both tachs worked but the factory one was never as responsive as the Sun... i had the second needle on the Sun set right on 6k cause that's where the 340 liked to be power shifted. but i do now remember that the factory tach wasn't any good. it was too small to see also on those dark late nights of street racing.
take care..
