I had a 71 lemans for 9 years, now I wish I had it back.
I like the 71 because the huge grill opening would be a great place to put a turbo intercooler.
Here is a picture of it next to my Z28. I sold the Pontiac because the Camaro could out perform it in everyway. I later sold the Camaro because it was a lemon, I don't really miss it.
The best mod I ever made to that car was the 15" wheels with Radial tires, I orginally had 14" wheels with Firstone Supersports. The handining increase from tire and wheel change was amazing, those old bias ply tires sucked.
After changing the tires and wheels I decides to upgrade the whole front suspension. At the time HO racing (Herb Adams) was one one of the very few upgrades. I got the full polygraphite front end kit will new everything, springs, ball joints tie rod ends, center links... and I could barely tell the difference driving on the street. 12 years later and you have a lot more suspension option choices.
