That kind of power from a Malaise era 4 banger is not too shabby at all. Why do I have a feeling there are going to be a bunch of people that are going to call it under powered and complain about lack of a V8?
FYI the K-10 with a 350 in 1986 was pushing 165 HP at 3800 RPM and 265 Lb.-Ft of Torque at 1600 RPM so it was probably even more lacking than the Toyota once you look at the 6100 LB GVW.
I loved these things. So underpowered by todays standard I would love to have one come back with a turbo 4 or a V6. I forgot about the turbo 4 that was available for a bit. I definitely remember the regular 4 and V6 models. I wish we could get a simple truck around this size today without the bloat of tech and simple price.
I bought a 1984 base model in 1986. It was totaled with front-end damage and a slow rollover on one side! New front sheet metal and some bondo and fiberglass repair and it was ready for paint. I drove that daily for the next 8 or 9 years. It was terribly under powered, 65mph on level grade with the pedal mashed to the floor, and when towing anything it was impossible to over 55mph. No AC, and no power steering. Parallel parking was a real challenge. Still, it was my beach and ski machine, making many a trip to the passes and the coast. Finally sold it as my future wife had a 1993 W350 (Cummins) from her father. The 4Runner was awsome and horrible at the same time. I miss it often.
