build date ? Mine is 1/31 and the engine builder said it was cast. Could have been swapped when the original was ground in the late 70's ??? Gone now, with the stroker kit installed.

I don't know how to decode these.

Assembly code stamped on the pad will start with a T and have 4 numbers after it.

In this pic of your 427, the assembly, build, date is December 4th.

Difficult to see on my pad, but it is T0130 Jan 30 CRT
