1980 Pontiac Trans-Am Info

On this page I share as much information as possible about the 301 Turbo. All the information I share on this page is what I had to search for and collect from various sites while fixing my own 301 Trubo. I hope these helps others to tget ther 301 Turbo back on the road.

While assembling the engine I was not sure where many of the parts must go. I uploaded all my pictures on one pages. These helped me a lot to find out where parts must go. I hope this will also help somebody else. Click here to view the pictures.
