Tach help
I have a '71, 350, with a distributor. The previous owner put in some kind of tach kit and the tach worked for about 3 weeks. I want to fix the tach but my mechanical experience is very limited.
Are there any tach manuals or anything available that I could pick up to help?

Re: Tach help (ridadyna)
Your best bet is getting a tach from 75-77 vette and installing that....
while you are at it, update to an HEI dist.....
ditch that old expensive unreliable mechanical tach....it's not worth repair....

I have a shop manual which is fully illustrated, but I don't think it's an assembly manual where it tells you how to do everything. Where would I get one of these?

Alwyn, about 5 years ago or so those dist main shafts for tach drives were about 80-100 bucks, and the rest of the parts were not cheap either....
I really don't know about today, but the issue of reliability still remains...
much less accuracy....

Re: Tach help (ridadyna)
I disagree with the negative comments on the non-hei distributior as well.
E-mail me offline and I'll walk you through the repair (no time for online pi$$ing contests).
I'm not aware of any manual that covers mechanical tach drive distributor repairs in detail.
There are some web sites etc that cover modifications, but these are not useful for basic troubleshooting & repair of the mechanical tach drive dist.

Re: Tach help (Alwyn678)
Thanks for the site. I'm sure I'll order from here.
I'm not sure if I'll the HEI route or not because everything in the car is still original. I'd like to keep it that way until she dies and I have to rebuild.
