Thius 1962-1974 Tach Drive Conversion Distributor is a great replacement for the factory points type distributor.
We have sold many of these with no complaints or returns. A high quality part, indeed.
Now with a simple distributor swap you can get all the benefits of HEI technology plus performance enhancements on top of the original HEI. For example the original HEI had a 38,000 volt module, pickup and coil, this unit provides 50,000 power packed volts! The original system had bushings in the housing, this model has needle bearings for smoother operation and longer life. Plus, this one-piece distributor has a 4340 hardened steel cam gear for use with all roller cams and brass terminals in the distributor for greater conductivity than the stock aluminum terminals. So when you compare this tachometer drive distributor to what your car came with you're getting a tremendous hi-performance distributor that eliminates the points and coil and gives you all the firepower you need for your Corvette's ignition. This unit simply bolts into place, all you have to do is run a 12 volt power lead to the distributor.
