Enjoyed driving the truck for like one summer after all that work.
Really missed the fact that the engine ran smooth, and didn’t have a lumpy cam.
Came up with a plan....but it was gonna be expensive.

Found a used GM 572/620 for sale that was four hours away from me.
When they wife gave me the “ok” to buy it, I wasn’t gonna wait and ask again to be sure I heard her correctly.
