Hold everything.

The cast date is L104...Dec 10, 1954
The valve cover plate on the side extends from distributor ledge upwards to above the spark plugs. A sure 216? and then, It has an oil pump and sump screen appliance. The presence of the oil pump indicates to me this is a factory engine., but not a babbit, and maybe low pressure in a 216? But it is more like a hybrid...I mean, a 216 in 1954?...and the receipt says 235t. It is handwritten, not computer. I mighta overpaid.

Patrick's says 3701946 Is a Babbit in 1953.
