Remanufactured 360 with spun bearing.

I'd be tempted to buy a new rod, or at least a known good used one. Years ago I had a rod "reconditioned" and the machine shop ASSURED me that it was "better than new." I can't prove the rod was the problem, but the next time around the engine grenaded. This was the original 6 pack block in my 70 RR. I removed the Edelbrock, distributor, and valve covers, and threw the rest in the garbage.
