This past weekend I picked up a Chrysler 35 HP that is locked up. For $50.00 I figured it was worth a shot to try and get it unlocked and running. The cylinders are soaking in CRC 6-56 right now. <br /><br />The model number is 355HC and serial # is 319?. The last number or numbers are missing. I'm guessing it's in the ball park of 1971.<br /><br />Can anyone tell me for sure?
