Basically I was the first to get a set of custom rods made so Cunningham was the place that made them. Pauter now does it cheaper and quicker. As far as cryo goes, I had the entire rotating assembly cryo'd- crank, pistons, rods, pins, rings, flywheel, and pressure plate. And for those lucky enough to remember my hub failures at SZ last year, I had some hubs treated as well. Do some searching for the S/C kit and you can find them around 3K here and there.
