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.



I was thinking the same...for stock stroke, why go with a suspect chinese eagle cast crank over a stocker?


At the time the Eagle crank was cheaper than having a stocker sent out for crack check, stroke equalizing, and indexing. As I said earlier this was before the Eagle cast crank reputation was well known. Would not buy a cast Eagle crank again. Thinking I might just tear this thing down and do the 4" steel crank. Don't want to ventilate the pan.
