The 360 build that has more turns than Willow Springs

The engine that the red balancer came from was a Magnum. It had the Magnum intake pattern, the rocker arms on studs, the different balance factor but....NO casting date. Instead, they had a weird coded stamping below the left head on the front. A "1" in the stamping indicated a 1991 or 2001. I assumed it was a 1991. The engine actually belongs to FABO member @RBConvert , we are rebuilding that engine at the same time we are doing mine, both here in my backyard shop...

The engine was standard bore. The machinist confirmed it. That is why I thought it might have been an early production 5.9 that was pulled from stock and used in the Mopar Performance crate 360 program.
I could be wrong about the history but being standard bore, it was never a junkyard engine.
