i went with the prc stage 2.5 5.3l heads and ms3 cam
couple questions....i also have an ls6 intake, 1 3/4" LT's and true duals
do you think i need to get bigger injectors now or are the stock ones ok??
also .....the car weighs less than 3000lb .....when im on the drag radials the stock clutch slips and i was thinking of going ahead and buying a new clutch..... i want it to take drag racing alot but would like it to be street friendly also ......what do you guys recommend

Get 42lbs now, they're like $320 for some Racetronix/Delphi's. I didn't and I am pretty sure you will be making more power than I am and I was triple digits duty cycle on the dyno.
I went with Monster Stage 4 because it was the same price as Stage 3 and holds 775 lb-ft. I would not recommend this for the street though. As it heats up, SOB grabs and grabs HARD. Only thing I can do is rev it up and dump the clutch and sputter away. Took some getting used to for sure coming from stock.
When I originally was dyno tuned, we could not get a 4th gear pass to rev to 6800, the stock clutch would slip @ IIRC, 6400 everytime. I could not enjoy the new found power of the H/C with the stock clutch. I replaced that and I still cannot enjoy the power, fully, until I replace the injectors! I won't do more than 2 gear pulls @ WOT due to the duty cycle, and that is more than I should with triple digit duty cycle.
