You can get a hei with a mechanical tach drive here for 169$

only thing to watch for is the HEI fitting under the 74 factory chrome shielding if you want to keep the shielding - not sure it will fit. can take a look at 75's to see what changed . . .

 

if i were not to use the machanical tac thing what would i need to do?

 

What is the original problem? Some members here rebuild these. IE, Lars.

 

If you're looking to get away from the mechanical tach (personally I would not) you'll need to change your tach to an electric one. I have heard of someone that makes an electric that replaces the mechanical and looks original. Your original disty is probably a point type- there are many kits available to change it to electronic.
