How much coolant you have left in the Stillen system? Depending on the water pump pressure, size of the leak. You might have gotten lucky and did water injection. Cleaning the combustion chambers and the tops of the pistons. If the motor kept running. You should be ok. It didn't hydro-lock. That's BAD!
Used to take a water hose and spray it down a carb until water started to run out of the tail pipe of a running motor. Never hurt it either.
