couple of ?'s 4 n00by

no the only thing i wont install myself if my 373's i don't do rear ends b/c i have never taken one apart yet... but otherwise i will assemble the rest of the things like heads (they will already be put together) i heard of a brand of head called ummm AFR good head or no?

if your referring to what i posted. the gears are already installed in it. all you have to do is remove your axles, the the 4 bolts that hold the rear to the control arms (put aftermarket control arms on while your there), and the driveshaft. how easier could it be
 
Also with my 1988 mustang u thing my little 302 can take on an lt1? I should be running 270 rwhp and him same??? im not sure plz put in ur inputs always like to hear from all of u!

This LT1 you want to challange, what type of car is it in? Is it stock? If you're racing a stock firebird or camaro, your mustang will definitely give them a run for the money. If it is a modded LT1, that is a different story.

Have you ever run your car at the track?
