Bought this flatty today. Seller said his dad ran it in a 40 Ford years ago hauling moonshine in Georgia. The 40 got wrecked but they saved the engine and stored it. It is suppose to be a 40 Ford engine but it has a 48 Ford dist. The cast bellhousing has 59 cast into it. I am mystified by the aluminum heads as I have never seen a pair like these before. The following is cast on the head: SCHRAGER AUTOMOTIVE ENGINEERING CO. LOS ANGELES S.A.E FIRING ORDER 15486372 I would like to know more about these heads and the history of SCHRAGER AUTOMOTIVE ENGINEERING. Any knowledge you can share is much appreciated. Thanks.
