1974 dart, 4 Door SE
I just picked up 70 Valiant 4-door with 225 Slant 6 a few months ago. Not going this crazy with engine - The more I drive the Slant 6, the more I like it. I have an old 318 in the garage ready for rebuild if I ever needed to go 8 cylinders...
The 4 door thing is really cool - I've always liked their look. The wifes 74 Duster is a good looking car, but something about the functionality of 4 doors.
