I've heard of more Callies being broken, but perhaps that's because people use them for high HP applications.

You know with all the main cap issues the big blocks
have I wonder if some of the people think it was a
broken crank that broke the block BUT maybe it was
a broken main that broke the crank... I've seen plenty
of broken main caps on BBs

Probably
Or also the margin for a poor tune is much more profound and catastrophic at these higher levels IMO.
When I see broken rods, mangled parts, busted pistons, it seems to be a easy target just to blame the China rod, or inferior crank that caused the destruction. When I know running a bad tune out the back door will tear up the best of the best parts.
FYI
I had a 4.15 stroke Eagle Crank I used in a build back in "03" when there wasnt much else available and put hundreds on top of hundreds of pass's and thousands of street miles. Although that stock block based engine probably never seen much over 700-750hp, it did survive sucking the pan dry on one occasion turning the crank down .020+ and mag'd ok for several more seasons of abuse.
I can say that I personally have used a 4.5 stroke 2.2 journal 440 Source crank shaft for a several seasons of abuse with power levels at or near 900hp mark. This wasnt no one pass wonder either. IIRC the last race weekend at the Mopar Southern Classic two years ago I put close to 30 passes during the coarse of that one race outing.
Im not so sure that these off shore cranks are from the same foundry based stuff just reboxed. So Cat, Scat, Eagle, K1 are of the same quality in my eyes.
Yes some are finished better over all and diff places than others, but when I use the final product whats the diff between these cranks? In the end they are all checked, correct, and run either way.

has anyone seen a Crower billet break..?

Yes,that would be under"and others".We have seen many of the top fuel cranks of all brands that get circulated in race parts for sale that are claimed to be good cranks and are actually cracked when checked.A lot of guys will still run them in low Hp applications.WE won't.

Yep, it's the old chicken and egg thing! We had a main cap break in our big block once - the Eagle crank cracked in two places, but held together. How that happened, we'll never know! This was an older crank, from the mid 90's I think. We are still using the same block today! <= this is as close as I could find to a knocking on wood smiley.

...crankshafts as they break at the front hub...The only crankshafts, besides cast, that I have seen break like that at the snout, were used in high horsepower applications

---

Unless you're driving a blower with the crank snout, the front of the crank before the 1,2 rod throw, doesn't see any power or torque at all. If it fails there it was caused by a vibration of some sort. I've heard of more failures at the front of the engine than anywhere else. I like to blame the damper or tune (or excess rpm for the engine) for this type of failure but there is always the possibility of a defect.

The reason I am asking is because I have one in my 572 that's in my dragster.

I just wanted to know if I should pull this motor apart and change the crank. It only has 94 passes and seems like alot of work, but thought I'd ask the experts.
