1974 Duster
Somebody swapped that motor in. Though I have seen the wrong year motor that was correct for the car before.
My '74 Duster (G code car / 318 car) had a numbers matching 1971 318, weird right? The Vin matched the '71 engine. Some other mopar nuts/friends figured it was an engine that somehow failed to make it into a car in '72 (and '73) so they found a place for it in my car.
I still have the engine (torn down), but I've had 340's in my car since 2006 so the original engine just collects dust.
Edit :
Not all '74s have Front Bumper Shocks either. Mine had plain brackets on the front bumper and shocks on the rear bumper.
