How do I convert from points and keep my stock tach. Thanks for all the help so far you guys and gals are a great help to a newbe to vettes. :cheers:

Well, basically, you don't want to keep the stock tach,...that cable and drive and even that tach head itself now a daze are all too unreliable to bother with....everything needs overhaul and reoiled, tach needs taken apart completely because of a hidden needle bearing being dry...common to the speedo also, for needle bounce and squeeling.....the cable gear drive in the dist head is also a PIA and very expensive to repair on a bi-annual basis....
get a tach from a 75-77? vette and have over with it....it's electronic...
that goes with the HEI you want...

If I would switch to a Mallory UniLite what else do i need to do? I was just looking around in ecklers for ideas.

If your distributor is in good condition otherwise, you can convert it to electronic for way less than the cost of a custom HEI with tach drive. For about the same price as a tach drive HEI, you can go to an MSD distributor with a 6AL box. I disagree with Gene about the reliability of mechanical tachs. While any old component is more likely to fail than a new one, the vast majority of tach drive Vettes haven't had a problem even after 30+ years and many miles.

See Gene's reply. :thumbs:

Vrodder, have to say I disagree with you, really, as I have seen and heard enough of those shafts wearing out/damaged by the gears out the side...which are loaded with the cable failures, and then the end unit the tach itself.....after seeing my own vette, and looking at the damage/loading/design of the overall system....

sorry...it's an overall design failure just waiting to happen, and when such a good alternative...IE anything, just anything...electronic is possible...
considering the overall cost....I just can't see repairing that old mechanical monster....
