What is the center to center measurement of the Crosley 4 cylinder connecting rod?

If your after the center of the crank to center of piston pin-thats easy-2 1/4 inches-- the stroke of the engine.

Nice try Chuck but 2 1/4 inches would be the swing from top to bottom of a crank throw. I measured 4 1/4 inches center to center on a rod. I would not use the measurements to make a new rod since I did it with a yard stick. Do you need it closer than that?

Your right Jim-bad part is that I measured a rod-must have been a short one.
