I know it's not bike related but I'm trying to get the short block out of my garage. It came out of my 94 Silverado and had 112,000 miles on it. Nothing wrong with the bottom end, the valve guides in the heads went bad so I just replaced it with a crate engine from GM. It has the one piece rear main seal. I'll be taking the internals apart today so if anyone needs a decent block let me know.
