1974 Swinger...let the pain begin

I'm picking up a 75 Scamp that also has a 3 speed on the floor.
Is this odd for a Dart and espically a Scamp?
It's a 318 A/C car

I was always under the impression the 3 speed was a low buck thing, for those who couldn't quite afford a hot rod. But in theory the 318 was probably the biggest motor the scamp came out with so....
