NEV3R L8

I'm starting to look at my options for getting a cam installed. It will be on my DD so I want something that will be good for that but also I'd like to hopefully make 450rwhp but above all better times. I want something that I don't have to constantly replace springs. My mods are in my sig.

I've been recommended a comp cam 224/230 113+2 Made 432rwhp on a C5Z with headers and tune.

I would just hate to not like the cam once it is in. So I want to get as many recommendations as possible.

No one has a cam lol?

David,

I am going to have my Comp Cams XR275HR which is a 222/224, 566/568, 112 lsa installed with the matching valvetrain kit on the 19th. Will let you know how it is.

The XR275HR is listed as the biggest mild cam as the power band is 1800 to 6500 which is where I want the power. Any higher and I will have to go with a stall convertor.

I'm trying to learn as much as I can about cams but I'm still a little confused. How does the 224/230 113+2 compare to your 222/224? Is it bigger or smaller? And what numbers are you hoping for?

HawaiiC6

The 222/224 and your 224/230 are the duration of the cam, your 224/230 is a bigger cam in regards to duration, with that duration you will probably have a lift of around .600 which is big and close to a racing cam. The 112 and your 113+2 is the lsa = lobe seperation angle mine is tight and I may lose some vacuum pressure but I will have good top end power, the wider the separation the more vacuum and more lower end power.

most power/quickest time?

Get a 280/290 @ .050 with .800 lift on a 102 lsa. you may have to do some other modifications to your engine, however.... ;-)

most power and still be able to acutally drive the car?

get something like mentioned above around a 230 with .600 lift and a 114 or 112 lsa.

learn about cams by searching google for "how does a camshaft work"

duration is how long the cam keeps the valve open (in degrees of rotation)
lift is how far it pushes the valve open
lobe separation is how far apart the peak open points are between intake and exhaust valves on a cylinder
etc.
obviously you can't change one without affecting the other, hence the thousands of profiles available.

will you notice a difference between one companies cam and another? well, as long as the specs are close, no.

Anyone know the specs on the G5X3?

BTW - most power/quickest time are two separate issues. If you are only talking about 1/4 mile times, they may be directly related. But 0-60 times favor torque over horsepower. The cam that gives the best peak horsepower may give slower 0-60 times. Be careful what you wish for.

NEV3R L8

Well what would be cam for the best times. I don't want to get something that I won't like so I want to be sure I do it right the first time.

You would get much more information and response in the tech section. That being said, especially with cams, do not go on opinions alone. Find someone local with the cam you are considering, and go for a ride to see how the car behaves. It will be a costly and irritating mistake if you have one installed and don't like the lope/shaking, drivability change, gas mileage difference etc.
