Question what is up with my car

(long) ok, my car has so many probs i dont knwo what to do with it, like to start with my rear end whines like no other really loud and the owner who owned it before me said that the guy before him said he had broke it at a drag strip and it had got a new rearend, and i dont think it has gears casue going like 65 or so and im at 1500-2000 rpsm so i really dont think it has gears, so do u think the new rear is messed up?

ok and another thing is my car wont even spin a tire, like even turning and i can get on and it wont kick the back end out out all its real hesitant and takes a few seconds then it will go it doesnt go when i give it throtle it takes a few second sthen it will go, it has no power at all, v6 mustang beat me by a car or two thats how bad my car is.

and the tranny was acting up really bad about a month or so ago and not shifting, until one night me and my buddies was driving around and it had a bad back fire or somehitng but it sounded like it was in the engine it made like an explosion sound an the it sounded like stuff was falling on my hood, and then it ran like total ****, then after a few mintutes it returned back to normal, not normal but not as bad, so idk what do u guys think is wrong with my car? oh and also my car has headers, chip and all so should it really be this slow? and the engine was rebuilt 30,000 miles ago along with the tranny

At 2000 rpm in overdrive on my LT1 Firebird, i'm cruising at 85 mph, so yes I would say you have problems or a higher gear in the rearend, and if it's whining, you do have a problem there. If it has higher gears and you can't spin the tires, there is a serious problem, my 2.73 gearing squeals the tires without even trying.

You say it has a "chip" in it, is it a '93 model? or do you mean the PCM has been tuned. Firstly, I would check the PCM for any codes.
