This is one of my current projects - a 1964 Plymouth Belvedere, factory 318, pushbutton automatic. I am currently building a 1964 413, which will be highly modified, and a modified big-block 727.
I am also replacing the rear end with a 1967 Belvedere police car rear end, which has a posi with 3:23:1 gears, a 1-inch sway bar, and large 3x12 brakes.
I am rebuilding the front end, and am updating to disc brakes. A fresh coat of paint and some interior work and - voila! A cruiser's delight!
