ok, i have a 89 cutlass ciera with a 2.8. i am thinking about geting the 3.8 supercharge III engine, now i am not sure if i would have to change my tranny. and if i did i am worried about my half shafts. not sure if i could get half shafts the right size to fit to my car. if anyone has some advice on this and help me out that would be great. thanks.
