A 1951 Crosley wagon is cool in that quirky oddity sort of way. But you'll probably want more grunt than the original 26 HP motor. Well you could try to shoehorn in a small block V8, but that would just take away some of the offbeat Crosley charm. So why not use a Harley V-twin? With 110 HP, it's hardly a slouch in the little 1600-lb. wagon. Now the Crosley can cruise Woodward and hang out at Sturgis. Check out the whole build process here.
