As far as swapping gears go's, You can dop the pumpkin and take it to a tranny shop and have them do the swap. Unless of course, you have the tools and know how to do this. I have 3.27's in my 95-5. They're wonderful, very big difference. For my car, I just pulled a pumpkin from an older sc with low mileage and 3.27's in it already. All of the pre93 pumpkins have track-lok as well. I am also using mobil 1 synthetic fluid. No complaints from me.
