New Chevrolet / GM Gen III LM7 5.3 liter LS engine block. Brand new , not reconditioned. Factory cam bearings installed. I bought this block to build a backup for my drag motor but I never needed it because my existing engine refuses to quit. Smokin’ deal at $600. It’s stored indoors on a dolly and I can help you load it. For an extra couple bucks I can deliver in my truck.
