1. Bump the timing to 14 degrees, FREEBIE.
2. Best bang for the buck is gears (3:73's minimum), roughly $400 out the door (gears, installation, lube, everything).
3. Off road X-Pipe, roughly $200 depending on brand.
4. Pulleys, around $75 can find them in the classifieds for cheap.
5. Cold Air, make one yourself for around $15. Type Cold Air in the search feature of this forum for more info.
6. Tri-Ax shifter, $180. You want to bang the gears at the track correctly with crisp shorter shifts.
7. Nitto Drag Radials, $120-$150 each depending on size.
That's a little over $1000 and should get you into the low 14's at around 96-98 MPH.
Don't forget to remove some weight. Vacuum the entire car. Remove the jack, spare tire and tire iron. Remove the dog bone on the rear axle. Get everything out the car that doesn't need to be there while going down the 1/4 mile.
