Tach talk
Noob here, for his B-day, I bought my son a tach gauge cluster for his 67 lwb 292. But, it was for a V-8. Ok, so that didn't work.
Generally speaking, is it hard to locate the 6cyl. tach cluster? He has been driving this 67 for 3 years and in Jan. he pulled the 292 and has been overhauling it. Bored .60, marine cam, 0 decked block, head milled ? (forgot), Stovebolt 2 pc headers, Offenhauser intake, 390 Holley, T5 tranny. And more. He is 17 and has done all of this himself. I'll try and get some pics of the 292. |

Re: Tach talk
Nice looking truck! Yes, it is tough to find the 6 cyl tach dashes. The only way to tell the diff is by the stamp on the back. Most were for a V-8...

Re: Tach talk
There are a couple of fixes besides paying the price for a stock 6 cyl tach, assuming you can find one
Most of the outfits that repair/restore dash gauges can recalibrate the tach circuit board for a different number of cylinders. There is also an aftermarket pulse converter that you can connect between the coil and the tach. It has dipswitches that you set according to a calibration table supplied with the unit (this step is necessary because it is a universal device used with other instruments besides tachs, like electric speedometers).

Re: Tach talk
My dads old 71 GMC had a tach in it with the monster 351 v6. May look in that direction

Re: Tach talk
Ray,
Thanks for the advice. Now, can anyone recommend a resto company to perform the upgrade to the 6 cyl.? Or an outfit that sells the pulse converter? Steve |

http://www.hemmings.com/classifieds/...pe=Instruments Unfortunately, I can't recommend any of these personally. The last one I used here in SF has since gone out of business. I would suggest finding one that is close to your home and telling them what you want to do so you can hear what they have to say. I am still looking for another pulse rate converter besides this one, which is kind of pricey and really made for a different purpose. http://www.atrol.com/era.htm Ray |

Re: Tach talk
This is more like what I had in mind for the tach pulse converter. It would be a better choice than the Abbott ERA and costs less.
