Cam opinions yes I know there a million threads
2003 2v GT
LTs, Intake, Plenum, Lower Intake, O/r H, mufflers, 4.10 gear, 70mm TB
I'm looking for a good set of cams for stock heads that will be friendly with nitrous.
I am going to be spraying 100-150 shot, I'm going to swap the springs and have the car dyno tuned in april right after I install the cams. What's I have looked at are:
CMS Stage II cams
MHS Stage II PI NA cams
Hi-Tech stage II NA cams
CMS Stage I cams
I figured I would shift at around 5700-5800 on nitrous to not put too much stress on the rods so my question is, the only time I am going to be really getting on the car is when I'm spraying and if I'm only shifting at 5700-5800, are stage II cams really worth it? I know they will produce more hp at higher rpms, but If I'm shifting under 6k rpms, am I really going to utilize the difference with the stage IIs? Thanks for input as always.

If you want to stay away from any possible ptv clearence problems i'd go with MHS stage 2's. I have full bolt ons plus a 100 shot, and these are the ones i'll be going with. CMS stage 1's would be good too. Plus you'll be fine on the stock valve springs, which saves some time and money as well.
If you're not going beyond 6,000 rpm there is very little benefit to going with the bigger cams. Also, you'll need to change the springs at that point.

I'm no nitrous guru by any means, but from what I've read about nitrous and cam selections, but looking between the CMS 1 and 2 cams, I think the lift and duration of the stage 2 cams are going to be more friendly to the larger shot you'd like to run.

That's true, but at a 100-150 shot it really doesn't matter.

BTW, I know this topic has been contested every time someone brings it up, but personally I believe any time you're swapping to a more aggressive cam, whether the manufacturer tells you that you can get away with it or not, you should be swapping to the better springs as well.

I talked to Jim Cushman told him my setup and it's a daily driven car so I dont want anything to aggressive. He seems to think stage 1s with stock springs and nitrous would be a good combo. I still will swap the springs.
