inconsistent clutch travel

Ok so i just had a new clutch put in my 1974 Plymouth Duster. The old clutch had a really smooth and consistent travel when pressing and releasing the clutch pedal. The new clutch has a smooth travel for about 70 to 80 percent of the way down and then it hits the floor, the same when releasing. when it hits the floor the clutch is fully disengaged. when i release the clutch it pops back a little and then i can control how much the clutch engages. it just feels different to me because this is my first car and only manual transmission car i have ever driven. any answers will be much appreciated.
