Well, it's been a few months. I got a good used tach on eBay. This one works. It's the closest thing to a speedometer that I'm gonna have, aside from the occasional speed check with my phone speedometer app.
I was parked for a little while because of a different problem. My dad and I have a '76 GMC with a 292 in it. We bought it a while back, and it had a brand new HEI distributor in it. Well, I had taken it out into the mountains a bit, and on the way home, that new distributor tore itself apart. The upper bushing went out, tried to lock up, spun the distributor, put all the spark into the exhaust, and overinflated the muffler. I was able to turn the timing back close to where it was, and drive to where I could get a phone signal. It was running on two cylinders by the time it finally quit.
I had to have my brother pull the distributor out of the rat, and my wife and her dad brought it to me. I dropped it in, and drove home. Here's my vote against cheap, generic distributors.
That distributor had about 500 miles on it.
So, the rat was without a distributor for a while, but I realized my priorities and pulled mine back out of the pickup, and put it back in the rat.
One of the best upgrades that I finally got done, was this:
That's right. I finally got new tires. Now I can finally drive it without worrying about the tires flying apart, and I can go normal speeds.
I put 481 miles on those old scabs.
