Tech, apparently some Small Blocks had the VIN or portion of the VIN
stamped at one of three locations.....my book claims such, the Mortec site says so, etc. I have never paid enough attention to anything but the pad in front of the passenger head to notice.

Mortec site says that "In later years, parts of the Vehicle Identification Number (V.I.N.) were also added before or after the Engine Assembly Date/Suffix code. In that case you might see "T0422TR 1123456789" stamped into the pad on the front passenger side of the block. Sometimes the engine V.I.N. was stamped into a different area of the block on the flange edge of the rear of the block, near the bellhousing mating surface. Sometimes the stamping is found above the timing cover mating surface on the front of the block."

Again, I have never paid attention so I cannot deny such....I do remember that Muncies had some derivative of the VIN also.
