Kristen, the shotgun motor is the Boss 429. Sorry, I had to say that since she already answered all of the other ones.
The street 289's and 427's (actually a 428) had undercar exhaust. They didn't have the fender flairs either (I really like that body style, often referred to as "slab sides.")
Ron- I got up 15 minutes before I was supposted to leave for school. I really, really hate being late, this is the latest I have gotten up on a school day.
Oh by the way, I GOT ACCEPTED INTO VOTECH!!!!!!!!!!!
