It is a real tripower car. The motor is not original, but is a 66 389ci motor. The 4speed & the rear diff are original to the car. Trans has the car’s VIN on it. Most of the body panels are original, except the driver’s door (someone backed into it when my dad was driving it 20+ years ago, so he got a nice replacement door back then). There have been alot of factory options added to the car, that don’t belong on it (A/C, power steering, power disc brakes, power windows, wood steering wheel, walnut shift knob, etc). It was not a heavily optioned car when new, however it has the very rare AM/FM radio option.
I do have the PHS documents, as well as a copy of the window sticker for this car. This certifies the car as an original tripower car and shows all options that it came with.
As far as numbers matching - '66 Pontiac’s don’t have a VIN on the motor, so this car could be passed off as a “numbers matching” car, since the motor (block, heads, intake) has a proper date code that matches the date code of the body. I am building the car for me & not to sell, so it really doesn’t matter. In the future, I am planning on building a mild, aluminum headed, roller cammed, 455ci motor for it & plan on obtaining another Muncie 4spd to thrash on, while keeping this 389 & original 4spd intact.
