Some may be interested in this. I need to figure out what went wrong. As this info might be of value to someone else some day. As the cause isn't real clear at this point. The oil level was on full. Glenn used Mobil one. The engine had about 8,000 miles on a rebuild. HV oil pump was installed. The work done appears well done by someone that does a lot of work on GMC's. Engine was balanced, APR rod bolts installed cost just under $200. Vary good quality bearings, pistons, and double roller timing chain. Heads have hardened seats with all new valves, and springs. The bearings tell a story that oil was in short supply over a period of time. In other words. It wasn't like an oil cooler line ruptured. Rods 1,and 2 were locked up. Rods 3, and 4 spun in their rods. Rod bearings 5, 6, 7, and 8 are lightly grooved. But 8 was in the best condition of them all. Mains are all groove. Pistons, and cylinder walls have scratches. Block is bored .060 over. Heads are in great shape. At thi
s point the crankshaft pistons, and block are now all junk. May come down that the heads, cam assembly, and water pump maybe the only parts that can be used again. Have an extra complete 455. Need to disassemble that engine to make a good short block.Bob Dunahugh
