F0626UH = Flint, MI, June 26th, 292 Manual Transmission. [1967 block]
F0627XAE= Flint, MI, June 27th, [XAE is a mystery] But it's the known original engine, a 292 L6 [1968] in a '68 C/10 Stepside w/SM465.
The upper listed engine I pulled out of a C/20 longbed stepside ex-Forest Service truck in a junkyard in Tucson in 1977. Coincidence they were built a year and a day apart.
The engine stamp is F0113TCL which would indicate a Jan 13 assembly date which is consistent with the Jan casting date.
