You're going to need to mod it to make sure black is still the fastest color!
New shifter is a must. (I found other things that needed mods)
Oh BTW, there are losts of go fast goodies for the LS(2 or 6). Heads, Cams, super chargers, headers, intakes........ What a wonderful motor.
This is a dangerous place, you will get bit by the mod bug if you hang out here too much.
