Hello, this is my first post. I have a 72 Gp with a 400 4bbl and 400 turbo trans. I've been restoring it for about 2 years.
As far as what your car is worth, I've seen 400 and 455 cars in the trader go for anywhere from $7,000 to $10,000. Thats restored or in great shape.
As far as parts go, I've searched the web up and down look'n for parts for mine. I found only 2 companys that cater to our Gp's.
Ames Performance Engineering free catalog Full size + Grand Prix
Performance Years Pontiac also their is a free catalog listed as Full size + Grand Prix
Ames has the most and they have the carb your look'n for.
Now for High Performance parts check out Kauffman Racing Equipment.
Or Jim Butler Performance, they are the ppl who know pontiac engines. They have stuff you can't find anywhere else. I guess if you own 2 GTO's you know this, I forgot about that.
I also have a question, wheres a good place that I can get pic's of my Gp hosted. I want to post'm for you guys.
