Factory Tach?
I have a nice factory tach gauge cluster and was wondering if you can hook it up to a msd 6al and a pro billet dist. I read somewhere that can't remember where but it said that you couldn't use the factory tach with anything other than points. Is this true? If not would love to get some info thanks.

Re: Factory Tach?
Mine has been hooked up to a HEI for about 15 years and hasn't missed a beat.

Re: Factory Tach?
I have also been running them on HEIs for years and never had a problem. Just plug into the tach terminal on the cap.
As far as using the msd with it, i can't help there.
