Well apart from the name it's going to depend on what the manufacturer is. Stage number all correspond with power levels higher the number the more aggressive the grind. Use the search function for more info as this has been discussed a few times before.

the higher the stage roughly equates to a more aggresive profile in respect to duration and timing of the lobes.

No, more aggressive means a more radical grind, as in more duration and lift. That definatly doesn't directly translate into more power. Cams need to be tailored to the engine they're going to be put in; you wouldn't want to just slap some stage III race cams into a stock zetec and be done with it, it would idle and run like crap. Cams shift powerbands around, generally the more radical the cam profile the higher up in the rpm range it makes its power. You will gain power up top but at the cost of torque. Unless you have just about every NA engine mod and only plan on running at the drag strip, you have no use for stage III cams. Go with a more mild street grind like crower stage II's or the like.

Stage 1 in an all motor set up will give you good high end power. Cams inprove volumetric efficiency and I think that anything past a stage two is for a heavilly built motor.

Stage 1 & 2 also gives you fairly good feel at idle. I have stge 1's with my SC and with a charger it basically looses some bottom end and gain some top end power.

My stage 1's pre sc really improved acceleration and torque. They are good for 6 to 10 HP gain maybe more when properly tuned.

i feel i should add that STAGE doesn't mean JACK $HIT.. it is just a way for companies to advertise the different grinds of cam they have.

also, ask for people that HAVE the cams in their motor.. for example. i used to have gude cams in my focus. those are pretty aggressive... they are just about as aggressive, maybe a little more aggressive than what crower calls "stage 3"... IIRC intake cam was .454" lift, 258 degree duration and exhaust cam was .400" lift, 238 degree duration.. my car DIDN't idle that bad.. and i DIDN't lose much, if any torque. my only other mods were 4-1 header, flex pipe and exhaust. trapped at 91mph. NOT a heavily built motor.. NOT all the possible bolt ons

keep in mind though. all motor power is the hard road. you can go with every bolt on possible, get cams and you will still getting destroyed by people with a turbo who spent the exact same amount of money as you....

Thanks for the info guys. I didn't know much about camshafts so now I know a lot more just by reading this stuff. I'll be getting the Crowler Stage 1 to run with my Nitrous Setup. I nice NX WET 50Shot with the Cams should give me nice gains and the Stage 1 cams should give me a good top end gain while off the juice.

Just one more question though, is the cams install hard to do. I'm pretty good with my hands and I've dealt with a lot of internal mods on my Stang so do you guys think that I could handle the cams install myself ??

I guess the hardest thing would be timming ?

Re: What\'s the dirfference between Stage 1 and Stage 3 cams !

if you follow the simple instructions for install its not too bad. the key is to make sure you have the cams lined up TDC or as close as possible... otherwise drivability issue will occure... get a piece of flat bar about 12 inches long and use that to line up the cams before removal. getting to the cams and removing them is easy as pie do one at a time. im sure someone around here can post a complete step by step...

don't need to line up cams before u remove.. DO need to find TDC and line up cams after you put them in. and need to go to dyno to adjust your cam gears .. dude i wouldn't use this thread as a reference.. its not very good.

your just creating more work for yourself...
but dont listen to me get a shop to install them....

Re: What\'s the dirfference between Stage 1 and Stage 3 cams !

yeah, and u actually lose power w/a cam that big w/stock springs and no lash, b/c that weak spring opens late and closes early, thus u lose power. i lash my stock cams, checkin them frequently, especially when the car was new and breakin in. when money is available, my STOCK cams will get better springs, retainers, and keepers etc. besides all these cams r a waste til u upgrade ur fuel/air system. its been proven already that 140-150whp can b pulled outta the stock head w/o cams as well.

good luck,

-Ult

why is that ? wont run out of injector until you got more than 150whp.. or are you talking about something totally different?
