Well, as an owner, I can tell you that stock power is between 45 and 50 horses (carburated).
I have an 87 that I have had for about 8 years, very capable rig, and will climb anything I can get 1 wheel on (welded front and rear).
Motor got weak, so it is currently retired ( but will be resurrected eventually).
The above rig weighs 1600 lbs, with me in it and a full 8 gallon tank. Very light.
I bought a wrecked out 2001 Chevy Tracker (THE JENNY) as the kids call it, off of Forrest Gump.
Going to be a heck of a rig someday, 113hp, fuel injected, automatic.
Am waiting on payday to order manual locking hubs, and do away with the air locked hubs, which currently are not functioning.
I'll post some pics of my 87.
Here's jls41 on a firewood run.
Here's her 1st buck loaded on the front, with the windshield up and bikini top on.
