No, the car seems fine (I did manage to blow the rear main, coating my clutch very nicely with oil, it's amazing though, as we get older we have better tools to work with. I actually changed a clutch last night on a lift! It only took four hours! What a joy!), as I said, once the 'Hill' leveled off, and the temp dropped down, the old girl zipped right along. The 'Hill' is on I-17 between Phoenix and Flagstaff. It traverses the Mogollon Rim, rising in elevation from approxitmately 1800 feet to just over 5500 feet in about 1 1/2 miles. It's a real bastard in a water-cooled car, but the T3 didn't like it at all. (I actually meant After TDC, sorry!) I had two manuals at my disposal when I was tuning it up before the trip; one said TDC (my manual), and a friend who's a mechanic who's book sad 7 1/2¼ btdc. He made a compromise and set it to 5, which worked fine until I started stretching the old girl's legs going on the interstate. Seems to be working fine, but she's throwing a lot of black smoke, that is intoxicating in the amount of gas fumes. Still getting 21+ in town, and 27+ on the road, though. Only other problem to mention is that occaisionally it will buck once (and only once) while whipping along the highway.
