I picked this 1927 Harley Davidson industrial engine up at the Irwindale Speedway swap meet today. I have never seen one before, apparently it is fairly rare. H.D. tried to boost their sales in the late 20's and early 30's by selling industrial engines to run just about anything you can imagine. It was unprofitable so they ceased production after only 2-3 years. This engine is in real good condition and is all there. It would make a pretty cool "boy racer".
