is my car in any way special/rare or more valuable than any other? 70 340.

I'm not a fan of pro touring either, but its a lot less garrish than pro street. That car looks like it was put together a long time ago judging by the patina(did I spell that right, I don't want to be called unintelligent). I love the flat black engine bay. It screams " I was built by a Camaro guy!"
Once you start getting stuff like that fixed, it will be a lot better.
My car's way more of an abomination than people who look at it know. Its all in the presentation.

Good eye. The blower was installed and the car was re-painted in 1980.

I started on polishing the blower... but it is a lot of work.
