Whats a 4 speed fell like

I got the opportunity to drive a 69 Dart 340 4 speed car about 12 years ago. Got to pull it up around 6000 rpm in the first 3 gears. We were haulin a$$. It shifted smooth as butter. I was hooked after that. About 2 years ago I bought a 67 Dart. It now has a 340 with auto and a stall. But now I have gathered all the parts to swap in a 4 speed. Dang I can't wait.
