My little hot rod is a Belvedere II with the side trim removed. The Satellite was a higher trim package on the Belvedere. It became a separate model in '68.
My hood scoop is incorrect for the car. The '65 used a big "hemi" hood scoop that was open all the way across. This one is a Max Wedge style scoop used in '63 and '64.

I converted this car to a 4 speed 6 years ago. I swapped it back to an automatic when I moved the engine back and down for better weight distribution. Moving the 4 speed would have been a major pain and it was far more difficult to drive with enthusiasm. If you tried to bang from 3rd to 4th under load it would top out the rear shocks and unload the tires. It lead to sideways excursions in excess of 80 mph. The rear suspension is great for a launch but tough for a 4 speed at speed.
The auto is much easier to live with and is being replaced with a 518 overdrive unit in the near future.
