Too slow?? Under geared for the tires? Or stock gears with oversize tires? My '81 4X was slow by car standards, but could get up to highway speeds on the ramp and held with traffic no problems. Now, my ('86) 4Runner, that's slow. I believe the preious owner, who did a head gasket change, put the thing together without knowing how to set the proper cam timing. I'll fix that as soon as this right shoulder get's fixed. The 'Yota 4Xs aren't really slow, unless they have problems. Get a list of mods done, it'll give you an idea of what you're getting into if you do get the truck.
