Doug,after cracking one $800 crank in 100 runs, and chewing up the maincaps in my nice new megablock back in 05, i spent 2300 for a Crower ccw. I figure guys that are somewhat commited to stock blocks might find it and reasonable alternative if it doubles or triples the life of thier block. A busted block also means a lost race and or weekend, all that machinework and parts, and block cores that are getting tougher to find.
