Engine/Transmission (1998.5 - 2002) is there a 4000rpm kit for the 24v?

is there a 4000rpm kit for the 24v? I noticed my friend has a 2005 LLY and it revs near 5000rpm. I know its easier for V-8 to rev higher than an I-6. I understand that there is a kit for the 12v and please correct me, it is mostly revolving the injector pump.



if there is a kit for the 24v, who supplies them, what does it do and is de-fueling a large obstacle?

you need a redline fuel box and some valve springs so that your engine won't eat itself alive but other than that you should be good to go.
