Sizzler - Let me preface my statement with the built Genesis engine I saw was outside the car on a dolly. With that said it might take 10 seconds if the engine were in the car since I would have to see the side
oil galley. On the Genesis block the side
oil galley is more pronounced and rectangular in shape. If you have or know an original S.O. it is distinctively different - thankfully. "It just tells" in responce to your question.
