the 20's on an SS are the same height as yours came with. when it comes to nitrous, nothing beats a 150 shot out of the hole. to fix your problem though, get around a 3k stall and you'll be happy.

 

thanks man. this thing is totaly streetable and gets 20mpg on the hwy. not so good in the city though b/c of my big stall. my stock rims it smokes em through 1st and busts a 2nd for about 2 seconds. my 20's isn't too bad, they spin through first and barks 2nd hard. the size is 20"x8" and the backspacing is 5"

 

related question...how can you fix the delay between when you stomp on the gas and when the power comes? you hear the throttle body open and like a full second later the truck starts moving
