Ames Performance Engineering is a New Hampshire supplier of classic Pontiac parts, with many of its reproduction pieces now made in its own shop. Its catalog covers Pontiac models from the 1950s through the early 2000s, while detailed product critiques help restorers judge the quality of each reproduction. The company also organizes the Tri-Power Pontiac Nationals, an event that began as Tri-Power Sunday in 1992 and has drawn hundreds of cars and thousands of spectators to Ohio.
