Well all i have to give for advice is the same as sleeperstyle, being as i do not have nitrous but know a good deal about it. First of all, im not sure what tires you have but you dont wanna spray 1/4 mile with drag radials and no rear-end. You can safely use it on the road though, just cant have drag radials or turn it on from 2nd gear forward. the other thing as sleeper said, after you get that cam you should get a tune. A tune is very important to making good reliable and safe power. I would take it to a tune shop, instead of the self tuning, they know what there doing most of the time. The other thing i would suggest is that if your going for quarter mile, forget the nitro for a bit and look into putting the power to the ground. After the Cam save your money for a rear-end with maybe 3.73's and then do a 100-150 shot on drag radials and you will be hauing some serious ***. But if your gonna get a rear-end and decide not to do nitrous then get 4.11's. Well good luck with whatever you decide on.
