Default Cable Drive Tach

Hello just a question here on a 72 with a cable drive tach, can I replace the distributor with an hei unit then replace the tach?

Yes, you could get an electronic tach but you can buy an HEI unit with a tach drive.

I'm facing the same decision. With the hassle of replacing the tach, I think I'm going to buy a tach drive HEI. There are some out there in Summit, etc.

yes you can replace the tach. I put a tach from a 75 in my 71, yours would be easier because you already have the white face gauges. mine are the green numbers and I had to swap the face over. yours would be a simple bolt in

I have the process of swaping out the tach face documented with pics if anyone is interested

for those wanting to convert their mechanical 1968 thru 1974 tachs to electronic operation (but would rather not DIY) - I perform this conversion. Email me for more info:
