MI Very nice restored 69-72 tach dash

[TBONE1964]

Here we have a ready to install fully restored 69-72 tach dash. All gauges including tach are good used GM parts that have been tested for function and the needles have been painted. This one comes with a NOS tach lens, a rebuilt speedometer head and new #168 bulbs. It has the same high quality workmanship as all of my restored clusters.

It will also come with a new tach harness that I make here. Your choice of point style or HEI terminal end.

Shipped and insured for purchase price of $550.00.

Thank you for looking,
Tom

It is not the weekend anymore but another one is coming soon

I may even throw in some LED's for an interested buyer.

I will even go one higher and give the new owner a 90 day warranty against parts. If any gauge on this cluster fails within 90 days of purchase, I replace it free and cover shipping both ways. No a bad deal for 40 + year gauges.


Thank you for looking,
Tom

I'll take it with a HEI terminal end harness. PM me your contact info and I will send you a postal M.O.

How are you incorporating the LED's? Any modifications required to the truck wiring or is this all in the cluster and basically plug and play?

Thanks!

Tach cluster is sold, pending payment.

Thank you,

Tom,

The cluster arrived today safe and sound. It looks great!



It will be going in my next project - Greenie - my 1972 GMC



Thanks for everything Tom.

Hi Wayne,

I am happy you got it and you are happy with it. It was/is a pleasure to do business with you. Greenie will be a very nice truck with you are finished with it. It looks like a truck nice to start with.

Take care and thanks again,
Tom

Tom do you run a tach filter with the HEI ignition? My rpms read high with HEI

I leave it up to the customer. It is a debate that is older than the correct color of dirt. Some will say they need a filter and some will not.

When you say your RPM reads high with HEI, what are you comparing it to? Did you just remove a point style ignition system and replace it with a HEI?

How much higher is the RPM than you think it should be?

If you need your tach calibrated, I can do that for you. A filter is more for helping with a smoother needle movement than correcting inaccurate RPM's. If your RPM's are consistently incorrect (meaning at idle it is 400 RPM higher than before), a filter will not help. Ignition systems create a lot of noise that can weaken the pulse signal and cause the tach needle to be erratic. Another thing to consider is you would more likely need a filter on a point style ignition than an HEI.

So in a nut shell, it will not hurt to add one but may not fix your problem.

Let me know if this helps.
Thank you,
Tom

I downloaded a calculator and witha 28" tall tire in fourth 1 to 1 at 70 mph it should be at 2549 rpm if I remember correct. I am at 3250. At idle it is correct. From what I read HEI sends a different pulse then a points distributor. These old tachs are wrong a lot. Everyone says put a filter on it.

851 RPM difference is a lot but not enough to consider it a 6 cylinder tach. For the price of a filter, I would say give it a try and see what you get. Do you know anyone with a Snap On digital timing light? They display RPM based off of pulse on a plug wire and are a great way to check tachometer calibration at a given RPM. I do admit that the old factory tachs do have some variation between them.

Can you share what you have read that states a HEI pulse is different than a point style? I am very curious about this as my understanding has always been that an 8 cyl pulse is an 8 cyl pulse.

I'm actually having the same issue with a after market tach I borrowed from a mechanic. idle it is right on but going 35mph in 4th it says I'm turning 4500 rpm's. he loaned me another tach to try but haven't gotten around to it yet.
