So go to get my first Inline today I get to the guys house and procedes to show me the engine. He pulled for a guy from a truck he was doing a big block swap. The truck was no longer there but he ended up with the engine.

He show a vid of the truck, the engine running, and then the odometer. The truck was a 1981 C10 with a 250 intgeral.The odometer said 18,000 miles. I told the guy probably 118,000. He said no the truck was an old couples and it was in storage till they passed. Everything like valve cover,oil pan, and stuff looked like it had been sealed with black silicone.I said nah somebody's been in there and they guy swore gm used silicone in the 80s. Your thoughts? I guess I will see more when I tear it down.

Sorry for the long story
