Looking at one. It's has 165,000 original miles and in Excellent shape. It has a 4.3l V6 Vortex.

What kind of reputation does the 4.3L have?

Pretty bullet proof engine. Its just a 350 with 2 cylinders lopped off. That engine should have the TBI, good low end torque.

My '92 2wd WT has that motor and still kicks ass.
