sorry to say it but nothing will really help much with 4:30's, a speedocal would get a little closer than a gear would.

yes, a speedcal will work on a 98 as long as its manual.

Well because the car is NPI its not quick at all but the 4.30's are freakign insane If I could get traction I could get off the line fast as hell but all I do is spin. I just finished my PI headswap so well see if that helps the 4.30's be able to allow the car to pull even harder. As far as Hp numbers and quarter mile time? I would have to say before the heads it was around 245hp and prolly around mid 14's in the quarter.
