Yes, the engine was running just a couple of days before it was removed from the S-10. The exhaust pipe is clean as a whistle inside which shows there was little or no oil consumption. I don't know the history of the truck, so I have no idea if this engine is original. My plan is to clean it up, paint it, adapt a carburetor in place of the injector body, and use it as-is. I also intend to change the water pump and pulleys so I can get rid of the serpentine belt and idlers. Then I can move the alternator to the other side and down low. If I run it like it is, the alternator and idler will be sticking out of the body.
