Reference Details
- Common issue
- Casting-date, assembly-date, or engineering-number evidence missing, out of sequence, or inconsistent with the car's build records; this does not by itself prove or disprove a specific car without VIN/document comparison.
- Confidence
- reported
- Correct value
- For 1970 Boss 302 blocks, reported casting numbers are D0ZE-6015-A, D0ZE-6015-B, and D0ZE-6015-C; the casting date is next to the casting number, and the engine assembly date should be later than the casting date.
- Where to check
- Casting number and casting date on the lower passenger side of the block near the starter; assembly date stamped on the front side of the engine or near the distributor area.
