Also, try advancing your timing to about 14, not at 1st though, just to see how it runs. A dude here did that on his ALL STOCK L98 and ran a 14.2@96 MPH.

Your 1/4 mile time depends highly on what gear ratio the car came with. If you have the 2.73 or 2.77 you will run high 14 low 15. If you have 3.23 or 3.27 you will run mid to high 14. This is assuming good traction as in a 2.0? 60ft and good weather conditions with low humidity.
