Thanks everyone. My thinking was these forged cranks are 50 plus years old with unknown prior use. It will be leaned on from time to time at the track. Did not want the possibility of metal fatigue in a high stressed part to be a weak link.
Well, I’ve got a whole rack of stock cranks with maybe 75,000 miles or less in the ten or so years they were on the road. They were pulled out, inspected, geased up and hung in a crank rack for the past 40 years. I can’t see much metal fatigue there in the rack. Clean them up, mag them and build them in my books for a build like yours. There are still some good stock and std cranks out there to be found. I’ve bought 3 in the last several months. So and old proven crank vs a Chinese guy behind a machine? I’ll take my chances with the old for the money. I’ve bought a Molnar from a stroker build. I’ll be assembling it soon. Looks to be a nice piece. I used one Eagle crank. It is still working.
