Last winter while doing a refresh on my 410 stoker build,my builder magnafluxed my forged Eagle crank.This is the crack he found.I was lucky to have caught this before catastrophic failure.I replaced the crank with a forged Molnar crank.You can really tell the difference in quality by just comparing.Oh I,ve also been running an ATI Super dampner for 12 year without issue.Molnar crank on right
