Here is my 1965 Belvedere.
I traded two motorcycles for it.
Its got a 318 and 904 combo with a 3.23 rear.
The engine and trans came out of a 78 Magnum Lean burn.
I still have the original 273 and 3 speed.
It has no rust except surface rust on the hood.
My plan is to:
Engine swap to 360 with 5 speed
Swap the rear to a 2.70 or 2.40 (Because Gas is going to go back up sooner or later)
Replace the Tail lights
Swap the grille to the Fury or GTX4 light style
Centerline black and billet Soft Tails
Update the front suspension and brakes with a Charger K member, Charger torsion rods, and Disc brakes.
Build a new center console.
