I would have your New eagle crank checked end to end with a Rockwell Scale for hardness. You will be surprised at the inconsistentsy. Also measure your rod and main journals, and order your bearings accordingly to accomodate clearances. If you use an Eagle rod and you have intentions of putting your engine on the spray, stay away from the lightweight series H-beam rods. The ARP 2000 rod bolt upgrade is a must. Also take them straight to the machine shop, break them down, re-torque, and have them checked for size. Eagle cranks and rods are great items, but they do require some attention.

X2 I agree with Josh here,this should get interesting if we can get actual numbers.
But then again some machine shops don't even know any thing about Rockwell tests.
I could go on here about some of these off-shore items but I am stoping now,You pay for what you get,like Josh said,you need to have these things,resized or even remachined,never take it for granted out of the box is fine,most likely they are not,and do require attention.
