I just got home from rescuing another early 61 409 historiccal artifact. Here's a few pics with more later after I get it unwrapped. It's date casted 12 November, 1960 three days before my other block which was 15 Nov and the Dan Gurney block was 16 Nov. All 3 examples were cast on the GM2 conveyor at Tonawanda and they all bear the same characteristics of the ground out and stamped 3795623 casting numbers as well as the four "X"s cast under the top of the bellhousing mounting flange, the small "L" stamped on the drivers side front of the block in the area where the "X" would later appear on the CFD blocks.
The really great thing about this example is the assembly stamp of T0207Q which is interesting to note the time between casting and assembly with the official production availability of the engine in early Feb, 61. It shows an original bore with about .007 wear and sleeves in two cylinders......It was magged but need to get it sonic checked to verify the cylinder wall thickness.
