I drive an 89 Jeep Wrangler 4.2L. Its bored out almost 100 over (thick water jacket!!), it has a new Hi-Flo carb, a hotter cam, new pistons, rings, rods, valves, the works. New tranny, transfer case, high flow intake and exhaust manifold, cat-back straight pipe and performance computer.
I've never had it dynoed, but if you wind it up and dump the clutch, it can get the front tires off the ground and it will spin the tires into 4th gear, so its got some punch!
Its also lifted 3 inches and is wearing 32's.
The above picture is fresh out of the shop after I had the motor bored out.
