Aftermarket Tachometers
Looking to buy a Tachometer to put into my factory gauge cluster, what fits? Is there any certain brand or manufacturer that everybody recommends? I have made a billet aluminum replica of the OE cluster that will be my finished product on the CNC mill at work, but am looking to fit all the aftermarket gauges in the original which is acting as a mock up. Once I have a tach, and figure out how to place it so it looks good, I will then outfit the rest of the cluster with the same style and vintage of stuff. Help out with details and tips if you can.
Josh

Re: Aftermarket Tachometers
I believe LMC has the "stock" tachometer. That will definetly fit.

Re: Aftermarket Tachometers
LMC and any other 67-72 GM truck parts dealer sells the "in-dash" tach.As for making a cup-mounted tach work,the standard size ones work.I dunno,are thet 3 1/4"?

Re: Aftermarket Tachometers
When I put together my 383 I didn't have a tach. I wanted to run the cam in EXACTLY how the manufacturer said so I bought an el-cheapo tach at Checkers.
Later on I wanted to buy a factory tach setup. About the time my factory (used) tach dash showed up there was a big debate on this list about the accuracy of 30+ year old factory tachs. I mocked up the el-cheapo and it appeared to fit pretty good. I had a factory gauge setup minus the speedo that I bought at a swap for $1 so I decided to cut it up to try this tach. I used the factory setup as a template and cut some holes in the $1 tin. I fabbed up a metal bracket to hold the tach and used the factory tach printed circuit to pass the wires through. I painted on some of that stuff you buy at Home Depot to dip your tool handles in to prevent any wear on the tach printed circuit. I also put a 4 wire trailer harness in line behind the tach so I can remove the dash if necessary. I also put in a "Quartz" clock out of a mid 80s GM truck while I was at it. That clock is suprisingly accurate. I tried to get a close up of el-cheapo tach. It says "Pro Tach".

Re: Aftermarket Tachometers
I have that exact same tach in my truck... it is WAY inacurate. Sometimes by a couple hundred, sometimes by over a thousand. (tested against my new snap on multimeter)
None the less... it is still in my truck. I installed mine in the inst panel, but I put it in from the front. I cut out the plastic lens, then I cut out the tin, and I had to hammer on the back plate of the inst panel, but it all works. I simply slid the tach in the bezel hole and it fits great. I know neither pic shows too well what I did, nor do they show how good it all actually turned out (I need a white face tach BAD), but they do give an idea though. |

Re: Aftermarket Tachometers
What are the measurements for the big gauge spots and the small ones? In your pic the tach is what diameter in inches? What about the clock/oil pressure/vacuum/ammeter? Looking to buy, not sure what size....

Re: Aftermarket Tachometers
I like the way the tach looks sitting on the colum. I have a similar tach to the ones pictured but I am going to mount mine on the colum in from of the hole.

Re: Aftermarket Tachometers
Zumo, if the truck is driven regulkarly at night, i don't recomend that. The reflection in the windshield is RIGHT dead center in your viewing path.
As for how do i know the snap on tool is right... I'd trust a $450 snap on tool over a 20 dollare 10 year old tach any day of my life. Plus, the tester is brand spankin new. I even had to order it and they were back ordered, so mine came straight from the factory instead of bouncing around on a tool truck for 6 months. |

Re: Aftermarket Tachometers
Honestly, i'll probably give it back to the snap on guy. I have a Fluke that he just tested and it is still dead on. It's about 8 years old, but if it is dead on, I can't see spending that kind of money on it... and i really don't need the tach setting.
Basicly I was standing on the truck itching to buy something... I just dropped another 2500 on my box adding on to it. I should probably lay off for a bit. |
