I had a 89 with a 4 cylinder, just as an about town grocery getter. That car kinda just sucked.
I've had a 67 Fastback since high school, that was my aunts prior to her passing. Just had a 289 in it, but I pulled the motor out and took the front end apart in order to restore it. That was 4yrs ago, haven't touched it since. Either had no money or no time. I need to pay off my other car first.
I have a friend who could be considered a Mustang freak. He's owned 2-3 before the current time, all of them pumped up. He currently owns two Saleens, one with a fairly built up 302, but that is his daily driver of the two. The other, is an 89 that will have a 408 stroker in it, and he's looking to get 750hp out of the rear wheels. That ones going to be the all-out street legal racing machine.
