First trip of any length with new motor-strong

In Dec. of 2000 we put a totally rebuilt 81 258 in my 1985 CJ-7, the old motor had 140,000 on it and was starting to feel a little tired, but ran OK, at least I was used to the way it ran. I had put only about 1200 miles on it since the rebuild, just wheeling in the Rock Garden and Chokecherry and a few short runs to the San Juans. Anyway, I drove it to Tucson and back this weekend, total trip about 1000 miles. Boy, does that new motor run strong, was able to do 75-80 on the interstate with no problem, pass or keep up speed going uphill. MY point is, if you are contemplating rebuilding, the stock 258 in fresh form is actually a very fine motor, I had forgotten how strong they actually are. And they are cheap and easy to rebuild. The only mod on this motor is a Weber 32/36, stock cam, exhaust and ignition.

75-80 in a CJ wow!

glad the engine rebuild went well. How is your fuel economy since the rebuild?

Fuel economy seems about the same, I've never checked it, but I'd say around 20 at a sane speed.
