cam for nitrous
I'm looking for a cam please help don't know much about cam specs. I have a ls2 a4 stock stall 125 shot and bolt ons. I'd like to keep my stock stall for now but put a nice came for nitrous. I would like it to be kinda choppy and would love the loud sound to please anyone that could get me in the right direction thank you all.

The good thing about nitrous is that it will make power with any cam. Whilst you could (in theory) optimise the specs for nitrous, I don't know anyone who does that to run a 125 shot (or even a 150-175). The folks that spec cams for nitrous are the ones who run spec built nitrous motors that are built specifically to run on (big) nitrous at the drag strip with a dedicated drag motor, who are using multiple/staged systems with 500-1000HP nitrous injection.
At the most, even if you were able to optimise a cam for your level of nitrous injection, you might see an additional 10 hp at the sacrifice of N/A street driving performance and mileage.
Also, since you only will be running nitrous a fraction of the time (at the strip, or at least until the bottle runs out) it simply doesn't make sense to spec a cam for nitrous on a street car, even if you were running a 250-300shot.
There are a number of nitrous gurus that will tell you that the best N2O combo is the best N/A combo, with the right tune of course (the right amount of fuel and less ignition timing)
Having said that, in my opinion, with the stock stall converter you need something in the region of 216-220 degrees on the intake, 220-228 on the exhaust and 112-114LSA.
Your best bet is to simply call one of the reputable cam companies that advertises on this forum and tell them what you have, what you want to do in the future and how you want the car to behave, and then have them spec a cam for you, along with all of the supporting parts you will need (springs, pushrods, etc.)
