Wow, what a blast from the past... Anyone remember Dave Strociek? Not surprised if no one does, one would have to be pretty deep into motorcycle drag racing back in the 1980's to have even heard of him. He drag raced Shovelhead big twin and Ironhead Sportster Harleys out of Chicago. He made a bit of a name for himself with his twin carb Shovelheads and his billet aluminum top ends for Ironheads.
Well, an on-line acquaintance out of Australia who races vintage sidecar managed to score a mostly complete Strociek Sportster motor. He is going to try to complete it and then compete with it. It displaces around 1340cc's, and he expects about 130hp on alcohol. I wish him all the best, it uses a lot of bespoke parts that appear to be missing. Not many were ever finished and made to run.
The astute among you will notice that the intake and exhaust have been switched to the left side. I'm not sure what he thought the advantages were, but it makes a lot of things kind of difficult. Gorgeous machine work, though:
