Wow, lots of F-Bodies! My first car was an '86 Cavalier 2.0L 4 speed stick. It was my dad's beater and I bought it from him pretty cheap. It was piss yellow with NO options. After I fixed it up, I quickly grew bored with how slow it was.
I found an 86 IROC in great shape except the people I bought it from thought it needed a motor. Long story short, it didn't but by the time I realized that I already had a worked 350 ready to go in. Still too slow, so I got a different cam, headers and 3" to the back with a cut-out and 3:73s. Had to have a custom stereo too, so after that I was pretty much out of money.
At 17, that car got me in trouble! It was worth it in the end though.
