Need more power for 95 vert????

Consider a Nitrous Express kit with all the saftey goodies.
You will notest a really good seat of the pants gain with nitrous.
Just make sure you get a decent tune after you install your
nitrous kit and get the saftey equitment your engine will be safe.
Start out small with a 75hp jets.It is very nice to have a convertible
but,your car is a heavy pig compaired to a coupe.

if your looking to keep the stock heads then your kind of limited on what you can do. The heads are major choke point in the system. You can get a new intake but it won't gain that much with the stock heads. IMO, get better heads

With almost identicle mods as you, but with an edelbrock performer intake (box stock), 65mm TB, shorty headers, 3.73's, stock flow tubes and tail pipes I ran a 14.3 at 97.2mph on street tires and a 13.83 at 98.55mph on nitto drag radials. The car had more off idle "kick in the pants" with the stock intake, as it'd blow the tires off with a stab of the gas. After the intake I gained more power up top and lost just enough down low that I didn't blow the tires off all the time which made for a quicker street and track car. My car would blow the tires off easier with the stock heads, cam, and intake than it did with my old combo of AFR165's, FTI cam, and the rest of the bolt-ons that ran 12.0's at 112mph.
