Rebuilding My Mercruiser 5.7L Boat Engine

With new parts and the previous videos I have made, I was able to toss this engine together quickly. This is a new (to me) 638 block that a machine shop had in stock for me. It is a 4 bolt main rather than 2 bolt main so that is a nice little upgrade. That, and the cam thrust cover was slightly different. They were easy fixed though and I reused all my top end parts after a thorough cleaning.
