Most of my driving around where I live is pretty flat, so I went looking for some good hills to see just what my all stock (except alternator) 30 Coupe could handle. One road in particular has a pretty steep climb that just keeps getting more uphill as you go, and is about 3/4 mile long. You also have to turn off of another road to enter so you can't make a straight on run with some momentum. My first try I revved pretty high in 2nd, then to 3rd and tried to make it to the top in third but couldn't do it. On try number 2, I switched back to 2nd much earlier and held 30 mph to the top. The engine pulled well, sounded good, and was smooth at 30 mph in second gear. How fast in 2nd gear is safe on the drive train?
