Valve spring replacement.
I am not sure what engine you were working on, it isn't the LT1. With only 40 psi, if the piston isn't at TDC it spins the crank. LOL,,,,,,,LOL,,,,,,LOL,,,,,LOL!
Actually, it doesn't matter if the crank spins, all of the valves are closed because the rocker arms are removed.
