Reference Details

Common issue
A 383, 440 four-barrel, or non-V-code Road Runner represented as an original 440 Six Barrel car.
Confidence
documented
Correct value
A 1971 Mopar VIN or body-code interpretation for this configuration should use engine code V for 440 6 BBL / 440-6 Bbl.; this narrows the prior generic V-code marker but still must be matched to the individual car's VIN and paperwork.
Where to check
Instrument-panel VIN plate, fender tag/body-code plate, door VIN label, broadcast sheet, window sticker, warranty records, and other original paperwork.
