i have a 88 mustang that speed density was added i can draive to gas station 5mi. away fill up go to crank car and it sounds as if battery is dead (brand new) motor turns over very slow, sometimes have to jump off or wait for 30min. or so..longer..checked timing and set at 10degree for stock have adjust to 12 degree no change...HELP...THINKING MIGHT BE STARTER....

 

that thinking would likely be correct. Since the starter is very close to the headers and exhaust a weak starter becomes weaker as it gets hot.

Once it gets hot enough it starts to pull a lot of amps on the battery because the resistance gets so high.

Options= pull starter and replace, or pull starter and take it to autozone and have a load test done on it. However a cold starter may test good .

 

ALSO I HAVE GOT MY HANDS ON A A9L COMPUTER N WIRING HARNESS FOR IT NOW WHAT ELSE WOULD I NEED FOR THIS CONVERSION N HOW HARD IS THIS...

 

Im assuming you want to do the maf conversion?

Maybe this will get you started and on your way
