Eagle crankshaft.......?
EAGLE crankshaft.
Has buy to itself Eagle crankshaft. (3.48 forged 4340 steel, from SummitRacing)
There are doubts concerning quality of manufacturing. (Made in China
)
Probably - it was necessary to buy Lunati or Callie.....
Who what can tell about Eagle? (good or NOT good?)
Balanced or NOT ????
Beforehand thank.

I am using 3.75 Eagle crank and H beam rod on my car. They are made in China but I have never heard of any body able to break the Eagle crank or the H beam rod. There are few guys on the F body crowd has made over 1000rwhp on Eagle crank and H beam rod no problems reported. Good luck man.
PS. when I bought my eagle crank. I got the internal balanced one. When the engine builder built my motor, they re-balanced with the piston installed.

I think it is a great crank, obviously not the best out there, but for most people under 900rwhp it should do about everything you would want.. several people in the FI world run that crank with zero issues.. I think rods and pistons let go before a crank does in the stated power range above.
I would get a zero balanced crank to start with if you are doing a 3.48" stroke, unless your using some seriously heavy slugs for pistons I doubt any mallory would be needed to balance out the engine.

I run a Crower in one and a Cola in another. I would not be opposed to running an Eagle crank with typical H-beams on a shorter stroke application. These heavier rods are a bit&h to get balanced on the larger stroke.

If iM not mistaken only the blanks are forged over in china. They are machined in california, and it's the machining that makes a nice part. Okay, the material quality and forging process due are equally important. But if each blank in really x-rayed like they claim then the chances of an inclusion within the material is very small.
But rest assured, the tooling and machines were most likely built and run by our fathers and grandfathers. As were the foundries. And then they were trained by a few of our craftsmen as well. We're doing a great job teaching china how to be a industrial equal. I hope they arn't just pretending to be our friends.
How do I know? the multiple spindle automatics I used to run, they very ones got sent to china. The operators and repairmen they hadnt already laid off (I got the first wave) were told they could move to china with the machines to help train the new workforce or hit the unemployment line. Another corporate triumph.

Eagle
Eagle makes some nice stuff that is extra affordable. I would not be worried about running an Eagle crank in one of my heavy nitrous engines. Depending on your price range I would also look at Ohio Crankshaft because you may actually be able to buy a better 4340 crank for equal or less money. Ohio Crank is a kick azz company who has their stuff together when it comes to combinations and rotating assemblies.

Eagle cranks and rods are OK. My friend is a local distributor for them and he runs them in his Super Gas car running 9.90's He has yet to break the stuff. Its heavy but works well. From my understanding, the forgings and rough machine work is done in the Chinese mills. As is the Scat stuff, and some Manley, yes I said Manley! However the final machine work and finish work is done here in the states. I wouldn't hesitate to recommend EAGLE for most applications especially for the budget minded enthusists. Not everyone can afford a Callies or a Lunati. Spealing of which Lunati has introduced their SLEDGEHAMMER line of cranks to compete with the EAGLE stuff. The only difference between their good stuff and the SLEDGEHAMMER line is the final machining and finishing. Whereas the high end cranks has much tighter tolerances and finishing, the economy line is limited to OE production tolerances. Nothing really wrong with that as your machine shop should double check any and all tolerances and fit before final assembly.

I'm not an expert on this issue but know a couple. They have told me that the material used in Scat and Eagle cranks is pretty good, but the machining tolerances used to be suspect. I believe most of the finish machining is now done in the states, so I assume the maching tolerances are decent on newer stuff. I have a Lunati crank for sale that I paid $1,600 for in 1999. It is a fine piece, but I wonder if it is worth what I paid?? Good luck.
