The Eagle 'forged' cranks I have used in Chebbys have worked fine over the years. I believe the problem with any of the after market cranks is the "cast" part. The quality of the material/alloy/carbon content/etc is another factor. I have used alot of Eagle products in X brand engines. I am a Mopar fan myself, but make a living off the X brand racers. I don't use cast cranks in anything unless the customer already has the stuff and will not listen to my experiences...then his warranty is GONE!
