I grew up in a motorhead family.

Alright.. time for a brother Dave story. I'm jumping ahead of a few siblings.. but if there's a 'motorhead's motorhead' in my family, it's Dave. The guy eats, sleeps, breathes cars, and ways to get the low-buck way to get more horsepower. My older brother Al, a Dodge mechanic at the time (mid 70's) challenged him to tune a car better. Al set it up on his Sun machine... Dave listened to it, laid his hands on the valve covers, went to work with a few hand tools. Half hour later, brother Al is "Holy F***! How do you do that?!?
So, anyways, when I was about 13 (so 1978 or so), Dave drives in with a 4 door 70 Coronet. The weird front end.. and the bright green paint. Ugliest car any of us ever saw. 318, 2 bbl, single exhaust. A slug.
Dave did his magic.. a little better, but still a slug. Then a couple days later, he tells me he's figured out his car, come for a ride with me. The only thing I notice, is that he kept the auto trans in low gear, all the way through town. 25, then 35. We get out on the highway at 55, he keeps it in low gear (auto trans). When the temp gauge is pinned, he punches it, still in low gear.. throws me back in the seat. Shifted to 2nd gear about 65.. chirped the tires. Car was crazy if you got it hot...real hot.
One day, I came out into the garage, and saw a wheel with threads hanging off. One of my friends told me the story.. Dave had a bunch ride with him, bought a brand new snow tire, mounted it, and proceeded to go out of town and burn that tire down to threads on the wheel, in that car. We got another brother of mine to go out to where that started... 6 miles of a one-legger burny.
