Had two of them back in the 80s. The white one had an Oldsmobile 403 engine, slow as molasses. The Bandit started with a 301 Turbo that was even slower, but got a 1967 Ram Air motor with some goodies from Nunzi in Brooklyn. I happen to have a few photos from that swap (we never took enough pictures). That was an honest 425HP car and with 3.73s was reasonably quick for its day.
I liked them, still do. They are fun cars with the T-tops off. Performance is meh.
