Going though batteris faster the a russan Porno goes through condoms!!!
 

I have a 1990 foxbody mustang with a bored 306 engine!!! T5 trans. BBk headers. But my car just seems to suck the life outa all the batteries I stick in it!!!! WTF is wrong with it??? Help please!!!

Have you checked to see if the car has something running when the car is off that is leaking power out of the battery. Also bad grounds will do all kinds of crap to a charging system. And is the alt working up to par?

sounds like a bad alternator or a ground short. Check stereo power wires especially under the carpet and go to auto-zone and have them test your charging system.

the alt seems to be running like a champ!!! i think its a ground!!! thanks for the advice!!!
