Some noob questions about 5.0s????????

Hello everyone, I just joined up here and i am probably going to be gettin a 87-93 mustang pretty soon. Now im a noob to mustangs not to cars. Just want to clear that up. Im comming from the other side. I have had 2 camaros and just recently sold my 95 z28. It had all the bolt ons and some juice But i am now finding an interest in to foxbody mustangs. What is the stock hp rating of a 302? Also with a 5spd what should it run in the 1/4? And with just basic boltons like longtubes,intake,slicks and a few other things here and there what kind of times would it run? Sorry for the questions, i just want to know a little more about these cars.

thanks for the info. Just what i was looking for. How much lighter is a lx from a gt? Also what is lighter between a hatchback and a notchback? Thanks again.
