I was finishing a dash for my chevelle and, after wiring all my guages, I found that the tach I got was apparantly out of a 6 cylinder camaro. Last time I checked I had 8 cylinders. So that means I either have to put in a 6 banger distributor or convert this tach over.
I know it can be done, because I made a crude tach one time using LEDs and some special IC from RatShack. This tach could be switched to 4,6, or 8 cylinder pulses. Unfortunatly this was done at a time when I had more money, patience, and brains (painting with clearcoat took care of the brains I guess). However, I do remember some of you folk are rather handy with electronics. I happily welcome your suggestions here, and no, I ain't buyin' a new tach. Thanks!
