I purchased an Eagle cast 4" crank,just for a mild street truck. I had it out of the box for 10 minutes admiring the workmanship,then quickly packed it up and returned it. I sold a MP cast 4" crank to a friend about 8 years ago and it broke a month ago. It has seen an average of 350 passes a year for 8 years,only runs mid 10's and rarely over 6500rpms,we didn't expect to run it more than a year or 2.
