Reference Details
- Common issue
- Treating same model year or visible component appearance as enough, instead of checking component dates against the car's SPD.
- Confidence
- reported
- Correct value
- MMC date-code guidance says component dates should be evaluated against the scheduled production date; it reports a normal engine casting-to-SPD range around 30-90 days, while Hemis have been found as much as 8 months before SPD.
- Where to check
- Scheduled production date on build documentation/fender tag, engine casting date, and other component date codes on the individual car
