Hei mech tacho distributor replacement
Hi guys/girls, I have a 72 which needs the tacho gear drive in the dist replaced to fix my bouncy tacho. It doesnt seem alot more expensive to replace the dist with a new hei mech tach one by the time they replace all the drive gears etc in the old one. Is this a good option or am I off on my pricing?

If it were mine, and the car is running well, I would remove the cable and old gear. Inspect the distributor main shaft gear- and if this is good just replace the tach drive gear and cable....
But it could just be a sticky and worn cable too...
Happy hunting...

There are about a dozen different HEI distributors with tach drive available from aftermarket Corvette suppliers or from ebay for about $100. They are Chinese, but I got one that is decent quality. If it bothers you, you can take off the Chinese components and get replacement parts- but these will most likely be made in Mexico.

Also though, you could buy a tach drive HEI, hook it up and find you still have the same tach bounce. I would try chucking tach cable in a drill and see how smooth tach reads before buying a dizzy...
