My mother had a '78 Aspen wagon SE like this (purchased brand new):
My sister coasted into the driveway and asked me to look at it. Short story...she said "you don't put water in a car"
Took it to school (auto shop) and we put in a 360, manual trans, ladder bars in the back '60 on the back, 70's on the front, tinted the windows, and reupholstered the rear seat (down) and sides in maroon velour.
Mom thought we were pulling the engine and rebuilding the slant 6.
After about a month and a half I brought it home (didn't cost a dime).
My sister never got to drive it again
