I would like to chime in here and say that this is only second Eagle crank we have had break in an FE. I can also say that this is to many. We are using the Scat cast steel and 4340 steel crank as well as the RPM 4340 steel cranks. We try to test this stuff the best that we can before we use a lot of it. I have used the 460 cranks in engines up to 800 HP with no problems up till a few years ago we had one of them break for no real reason.
I had one drag engine come back that broke a Scat cast steel crank but it was 4 yeaers old and it was built before the 4340 steel crank was available. We could use either a billet steel FE crank for about 2800.00 or the cast steel crank at that time at about 500.00. The customer decided to go the cast steel crank.
I hate when any part breaks and if we were getting the price of a NASCAR engine for this stuff we could double check everything and use the best parts available but we are not getting that money nor do many epople want to pay 50,000.00 for an FE engine. I do feel that all the parts we use in the engine will hold up to their intended use or we would not use them. I have used these cranks in stuff up to 700Hp and 6700 rpms over the years with just the few problems mentioned above.
I hope that there is something that we can do to help with this bad situation. I have gotten little help from ost part suppliers over the years. You know these parts are for high performance use and there for we do not warranty them, I have heard this several times. These are the things that make this engine business so tuff.
I have told several people that when you handle as many parts as we do you are more likely to get some bad parts. As far as the Eagle rods go I have really good luck with them. Most of the problems I have seen with them is a oiling problem or people not having the clearances right. Most people do not know that detonation is very hard on the crank and rods.
I will talk with Eljaro about some options he has. I would like to see the block as well because I have fixed a lot of aluminum part myself. If it can be fixed we can fix it.
