but doesnt the broken cranks or messed up cranks usually also depend on the builder too? as far as balancing and assembling it up when putting a block together?

Every Eagle crank that comes from China IS NOT as good as the rest.......no way, no how. Some will be perfect, some will be OK, some will be complete garbage. Its a gamble, just like anything else made there. They have no interest in making everything with the same attention to detail and scrutany. They suck at consistency.
I had 4,000 units of a product made there that I sold here, and I had to supply them with the proper nylon pellets from Japan because we caught them using Chinese nylon pellets, which suck *** and fall apart and crack after they come out of the mold and cure. But they don't crack apart for a good month, by that time they are delivered to the states and you're fucked..........I had to actually go to that shithole city over there and stay there for 3 weeks to watch them every day make our batch of product and pour our bags of pellets into the machine to be melted down.
China.....give me a break.

I was told by Callies that even on their less expensive line of Compstar products that they> (Callies)> supply the raw material for those products. So no, not all Chinese manufactured cranks is made the same. And just for the record, I've never had a Callies crank failure on anything...Blower motor, nitrous motor, whatever... And this is not a dig at Eagle. Just setting the record straight on some of the Callies comments.

If they don't know when you'll pulling pieces off the line randomly they will make every one the same and perfectly. Thats why we see no broken Callies.......
If its not done that way, the Chinese people will screw you, then blame you for it somehow, someway........because they get paid up front, usually 80% of the order, sometimes they require 100%.

I use alot of Callies cranks and will continue to do so-they are great pieces.And yes,not all chinese forgings are the same-the compstar piece is leaps and bounds better than most.

Just more likely to see scrap steel with all sorts of make ups getting into China supplied and forged steel.

The Compstar cranks meet the same QC requirements as the Callies versions. I toured their plant in OH and was very impressed with the QC.
Actually here are my Compstar/Callies tour notes:
Cranks:
4340 Material
<.0001" runout on journals
<.0002" variation between journals
All cranks magnafluxed and nitrided
Stroke length variation measured (no more stroke than +.001", no less than -.003")
Dimensions checked on Adcole and Faro Arm
LS Cranks rough balanced to 1750 grams
Rods:
Forged 4340 material true per ANSI
<.0001" runout big end and small end
Matched to small end weights first
Then grouped by big end weights within 2 grams.
Rockwell range allowed 34-38 (36-37 Avg.)
1 rod of each set is pulled to verify center to center length and rod parallelism(bend/twist)
