That's nothing. One of my friends, Chuck, always wanted an LT1 engine. He saved up and bought a new short block from Chevrolet. Came with a missing upper main bearing. Luckily, I was crazy enough to check everything.
Yikes. Glad you were there for that one. They were great engines. My bud with a Duster bought a 65' 327 Vette with 4.11's and bought a full crate LT1 and that car went 12.40's at 110 with nothing more then side pipe headers and slicks.
