It really depends on what you expect from it. If you are in a heads up class where you are limited to 1 250 HP plate there may be better choices but if you just want to go fast the N/A cam will certainly do the job. No one that runs heads up programs will give you this information. You need to contact a good cam grinder. They will be happy to sell it to you.

I know some very susseful NOS racers that ran a bunch more than a single 250 HP plate system, they spent thousands of dollars expermenting with all types of different combinations and they ended up using a N/A SS style cam after trying all of the NOS grind cams 
There is a point where the C.I. and the intended RPM range will come into play, especially on the lobe seperation angles

A lot of N/A cams, especially for Mopars, seem to have very short LSA numbers. With very much of a nitrous shot, all that overlap, just sucks the nitrous charge straight out the exhaust and you don't get all the benefit. Will it work, obviously it will. Will it be optimum for nitrous, no it won't. Given the near exact specs, a longer LSA cam will be better for nitrous than a short LSA cam everytime.

you're going to need AT LEAST a 3/4 cam. and stage three rods, or she may blow.

I agree with Monte here extra lobe seperation is your freind when running nitrous.
Some run more exhaust duration to. I think you can be conservative here on some of the heads that have good flowing exhaust characteristics. My CFE W8 heads on the small block nitrous engine I ran could not get enough exhaust lobe duration. The heads were designed purely for NA combinations and only have a 1.55" exhaust valve. I simply had the cam grinder put all the lobe seperation and exhaust duration physically possible in using that core. We just went back and fourth on LSA and Duration trying to find the sweet spot. If I told the specs you would swear it was an IHRA pro stock cam with a huge LSA.

Thanks for the input! Can anyone recommend a cam grinder that would help steer my combination in the right direction?

NICE INFO!!!!!!!!!!!!!!
Get over yourself. You ran a 8, that dont impress me much 
song Nitrous cams should have wider LS angles to help prevent the nitrous from being sucked out the exhaust at overlap. The overlap Pulse can/is Very strong in a well set up NA motor.
A nitrous motor doesnt need or want as strong a pulse IMO, A wider LS helps with that.
But for mild nitrous combos NA cams can work just fine as most are around a 108 to 110 LS anyways. miker

I understand what you are saying but since you feel that way you may be better off saying nothing than being purely negative.

You ADDED To the post??????!!
You stated :DEAD WRONG!!!!!!! Thanks!! That helps alot
Now THATS!!!!!,About your EGO!!
If you really wanted to help, You would just state that Nitrous combos like wider lobe seps.
Its NO big secret
And in case YOU dont know mild nitrous combos can work fine with NA cams around a 108 to 110 lobe sep.
And with your comment of Have a nice day,
Is That nice enough, No , As it wasnt sincere!! But you know what, you can work on that.

I think the post is asking for suggestions on a Nitrous cam grinder.Do any of you guys have any favorite cam grinders that are familiar with mopars and NO2.Or if any of you either sell or grind or spec your own NO2 specific cams now would be a good time to speak up.I think he would pay for a camshaft.

You havent stated your combination???? So What is it??
If its a mild nitrous combo, a regular NA 108/110 LS cam will work fine.
But Comp cams for one, can grind you anything you want.

Re: Nitrous cams??? - 10/29/09 09:21 PM
I think some exhaust flow #s would help a lot on pickin a nos cam , if you dont have any flow info , head type and valve size and if any port work has been done , then some basic exhaust system info , headers, open or muffs ect...
