i got a 89 iroc-z 5.7L with 240hp(soon to be over 350) black t-top pretty much all stock... im extremely happy with it...

so what do i do now... really wanna get a stereo and 3" chromed straight line pipes...

so what do i do?

 

Do a complete tune-up. Do plugs, wires, fuel and air filters and change the diff and tranny fluid. Then buy a new coil. The one on your IROC is probably cooked. See if it has any codes stored and fix all that before you start to mod it.

k... thanks but about how much will that be?

 

If you are doing it yourself it will be about $200. Maybe one of the guys in your area would be willing to help you out.

And get the MSD Blaster Coil.... it is about 80 bucks but worth it...
