Is anyone else worried about the cast eagle crankshaft at those power levels? I know it's stock stroke and stronger than a 4" arm but still, my 4" eagle broke at under 480 hp. Didn't dyno that one but the 440 in the truck now made 485 and it's faster than the 408 was. Just concerned for you, would hate to see your testing cut short because of a crap crankshaft.
