Randy - you are in Toyota heaven out there in California, you should have no problem finding a good one. I bought an '83 from a guy in San Jose and it was pretty rust free. A lot of people think the 85 4Runner is the holy grail, since it had EFI and solid front axle, there was also an Xtra cab that year, so you could have either the truck or the 4runner with solid front axle and fuel injection. As others have stated, if IFS is fine with you, then that opens you up to 86, 87, 88, and 89 4Runners and up to 1988 in the trucks. I think the trucks changed their design in 1989. Personally I like the 4Runner, top comes off, has some pretty decent cargo capacity. To your question about running 65, I have no problem pushing 65 in my 88 4Runner with a 22re. I have regeared to 4.88 with 33" tires. Mud tires are pretty loud on the highway though, I'm working on my sound deadening (I have no carpet right now). There are lots and lots of performance upgrades, but I'd say you aren't going to get much more out of these engines. My gas mileage is somewhere around 18 city, and I have gotten 20 on the highway.
