Callies Dragonslayer Crankshaft
Does anyone know more about the Callies Dragonslayer Crankshaft? Any experiences?
Seems like a decent price for an American Made 4340 forged crank, plus the Callies name doesn't hurt...

Dragonslayer
Spoke to Callies today. The crank is designed to compete with the foreign crank brands like Scat. They told me that it is a new crank that has been on the market for a year, primarily used in oval track cars. Here is a exerpt form their literature:
DRAGONSLAYER
Proudly Made by American Craftsmen
DragonSlayer crankshafts are made in the U.S.A. for American Racers. Made of Premium grade 4340 material, each DragonSlayer will outlast several offshore shafts. These shafts are machine to the tolerances demanded by today's high performance engine builder. Roundness and taper will be help to within .0003 in on all rod and main journal diameters. Our finishing procedures produce excellent load carrying surfaces that insure extended bearing life and trouble free operation.
Consider this is a long-term purchase, at Callies we manufacture components for long-term service. The unique Callies Dura-Tuff heat treatment will be there working for you even after .030 in regrind. Our 4340 material is considerably more fatigue resistant than any comparable shaft in this price category. The combination of our high purity premium grade steel and Callies proven heat-treat expertise produce strength of superior value.
Each crank is doubled checked for correct stroke, index and journal diameters. This attention to detail guarantees that your job of engine assembly will be trouble free
