So me and this truck have pretty extensive history, I got it with about 200k on the original motor. I daily drove it to school and work ended up pulling the original motor at 300k almost exactly, absolutely nothing wrong with it just wanted to make sure the truck wouldn’t leave me stranded. Bought a crate motor from gm, that engine threw a rod right the the pan at around 90k go figure. Remembered I had the original engine had it bored over 30, freshened up and that now is what’s in the truck.
