Look at the engine, if it's got a black or silver "Spider" on top with
a throttle body facing the front of the truck, it's the HO. If the
throttle body is vertical, it's the low output so to speak.

195 HP, 260 ft-lbs of torque in the early engines. The later 4x4
4.3's were 190 HP and 260 torque. Not much of a difference, I had a
94 with the HO 4.3 and 3.42 gears and now have a 2000 S-10 ZR2 with
the 190 HP 4.3, 3.73 gears and 31's and it feels like it has about the
same power and gets about the same mileage.
