224-220 581-581 116 with this cam what do u think
i need a good low end power and the most imprtant thing is idle i dont like shakeing

the 116 Lsa will help with the idle, the stealth cam is a great cam for a stock or near car. You have a muscle car, use it my friend. That cam may not make as much power as the one you have now. Always a tradeoff...

!!!!!!!!!

why you said that it will not give me power as my cam ??!!!!
it should give me more power all the way because it has bigger duration and bigger lift and the same LSA

sorry I misunderstood, I thought you were putting the stealth cam into the car. with that lift it will be harder on springs though.

Should make some sort of power. Might look into something with less lift so it's not so harsh on the springs. Generally cams with that much lift like fresh springs every once in a while, take that into consideration.

wesam

regarding the high lift i thougt i will be in the safe side because i have the patriot gold double springs which capable to handle up to .650 lift.

what do you think ?

Zcleanest28

Check em around 20k miles and see how they are. Spring in it now are most likely fine for the new cam but it never hurts to check when you take the old cam out.

That cam looks like it uses Comp Cams LSK lobes, which are very hard on valve springs. If your looking for a 'high maintenance' lobe, this is it. It's also a single pattern cam that is probably designed for a forced induction application where boost helps to compensate for the intake/exhaust ratio in the cylinder heads. You would be better off with a dual pattern cam, unless you've had some serious work done on the exhaust to increase flow and support the single pattern cam.

IMHO, I would look at a dual pattern with less aggressive lobe. Quieter valve train, less valve spring maintenance, and better performance.

Happy motoring!

I think the 116 Lsa is what would hurt power with that cam. Also with my cam i plan on replacing my spring every 10k or so. You can buy just the springs from patriot for right around 200 without the retainers and all too.

It is a LSK lobed cam, good Stealth and trq, -5* overlap, a bit more noticeable than the MTI S2 but still stealthy. I would recommend Patriot Extreeme Gold springs and 7.450 pushrods.
It will make more power than your cam, expect another 15 rwhp +/-

Why would you recommend a single pattern cam for this engine configuration over a similarly sized dual pattern?

I don't believe he recommended any cam, he simply gave his opinion on the cam in question.

Call it an opinion if you like, but I would consider concurrence and recommendation concerning valve springs and push rods as a recommendation. If the proposed cam configuration wasn't recommended than it should have been stated. The OP asked for thoughts on a cam, why would you lead someone astray by saying it will make more power, use X springs, and Y pushrods when it may not be optimum?

Are you Predator-Z's alter ego? I know he is more than capable of responding on his own.

Chill out dude. Geez.

I know you guys from Tejas don't like to be questioned because everything is bigger & better in texas but I gave you MY opinion on what Predator-Z was saying. I wasn't trying to read anything into his post

Quite to the contrary, I welcome constructive questioning which is why I asked the question concerning single v. dual pattern. It's all good.

PREDATOR-Z

At those size durations, single pattern usualy make more trq. It is a matter of valve events.
And yes it will make more power than the S2, why?
1- more duration (a 227 LSK is actualy a 228.x
2- more lift (which act like a crutch and let more charge in and out of the chamber.)

Myself, I wouldn't spec that cam but that is because I have my philosophies and experiences.
