I bought this 1969 Pontiac Firebird 400 from a friend for $500 around 1988. The original motor and transmission were long gone, so we used a Pontiac 455 from a 1970 Bonneville. You can see all of the specs here. I was originally going to paint it black with a red interior, that’s why you can see red in some of the pictures. After finding out the original color was Goldenrod Yellow, a favorite color, I went with that and changed the interior back to black.
