Tach help please

[oldtrux]

Anyone familiar with this tach? 6-8 cylinder??

I can't offer much in the way of which engine this tach will work for, but I can say it looks to be a later unit if its factory (i.e., without a transmitter box).

I did find this post that includes a picture of an OE-1 by member 1963c-10. Not sure if they are still on here or if that was their tach that was pictured. I believe what you have is a V8 tach, but I am not certain.

Take a look at this. Pretty sure the owner (Bob Ashlock) can set you up, regardless of what the original tach was for.

100% agree...just purchased one of his units and I am using an original 8 cyl tach with a 6 cyl. (It also will work with the HEI)

If that tach works with a points-type distributor, it should work fine on an HEI. There is a TACH terminal on the HEI, just run a wire there from the DIST terminal on your tach.

Ok,so I reached out to Bob at ashlocktech and he told me I should be fine with my DUI HEI dizzy. He went out of his way to research my dizzy to find out! As was mentioned above what a super knowledgeable and nice guy!! Thanks so much for the great info.
