Any engine builder worth his salt will check a cranks critical dimensions. I could never assume the quality of product unless you could be privy to the company's QC on the product. My personal experience with AN Eagle crank was it was not straight, journals not round and radiuses polished out. Atleast not good enough for a race motor. The crank had to be trued, cut 10/10, micro polished and heat-treated. To date, no problems and pushing dragster to 8.25/166, clearanced at 2 and 1 1/2 on 5-30 oil. I have been told, but have no supporting data, that the straightness issue is due to transport by sea in container ships. With cranks laying on their sides and the vibration/harmonics in the ship's hull cause a stress relief in the crank. Sounds like a stretch to me but sonic stress relief is a known practice. Also told the cranks arrive USA unpolished and are polished in the states. Lastly, in reading various posts, there seems to be a number of end users out there and machine shops that have commented on seeing out-of-spec cranks. Scott, can you comment on Summit's incoming QC on these cranks? I remember being at a performance parts supplier that will go un-named and they had a pallet load of Eagle cranks that did not meet specs and they would not use them.
