5.3 Camshaft Hello guys,
I have some problem been research about cam info. I kinda feel lost at the moment. I am trying find good cam to give good power and love the sounds when they do NA and boost later. I mean I could find right cam to run my na motor. Until Im saving up money to spend $ on turbo which I not have to change cam again. This is for my 2006 Silverado 2 wheel drive. I have problem to pick correct LSA I afraid to pick and wrong. I was wonder if I go 212/218 but LSA I need to know. Remember I may cant go larger cam because I do tow sometimes with Cheorokee Jeep though. To see if anybody more knowledge than me. Let me know. It will help me to make final decision before I order it. Thanks.

You may have better luck finding the specific info or talking to the right people over there. Then again You may get the typical Throw a 6.0 in it...
I choose the Comp Cams XR265HR-14 Part# 54-412-11
It Had the RPM power band I was looking for on a daily driver. After looking at a dyno sheet on this specific Cam Vs. stock it picked up all most 40hp across the board. Combine that with some head work, a few Bolt ons and a real tune. It should be real close to an extra 100 over stock.
You will probally want to also look into a mild converter. Yank has a 2600 stall specifically for truck applications. I believe this would work well for this combo naturally asperatied. If you go turbo though you will probally need a larger converter.
After talking with several people whom are actually running this particular cam it does not seem to lose any gas mileage which is another plus.
It also passes the Smog Sniffer Test. Another plus
Hope this gets you in the right direction on what your looking for.

The 02 up Z06 is a popular budget cam but it's not really that great from what people that have used it are saying.
For a turbo I personally would stay in the 114 LSA range this will help keep cylinder pressures in range under boost and still make good usable power down low.
The cam I posted above I personally believe would be a good all around cam for a stock truck application. NA and later for turbo use. You may look into a slightly larger cam.
Realistcaly though, if you plan to use the truck all around driving and for towing you should really look at the total package. That includes what your stock heads are capable of flowing for your cylinder size.

Yes Im from Pt.net there kept make me confuse with lsa. More likely I would go with 114LSA. I not want go run with 6.0 A reason Im keep with my 5.3. The reason I need to know if 212/218 is good to go? Yes I plan to built my 5.3 Iron Block to bore 346 cui. And Yes I will run a turbo someday. I was thinking about to run 3000 or 3200 yank if I swap to 80E tranny. Also will going to run with 317 heads with 72cc. I just wanted to see which a cam that I can use it for NA and later boost. Which I not have to change cam again you know what I mean?
I understand you don't want to run a 6.0L.
The 3000 and up converters will work better with a turbo, esppecially if you want to run a bigger cam. The #317 will drop you down on your compression big time, you would be going from 61 cc to around 71 cc. The other problem you will run into with those heads is sealing since the combustion chamber is so large and will over hang the bore. In other words you will have very little gasket surface sealing the heads to the deck. This will be a big problem under boost!!!
With a 3000 stall, turbo, and ported heads, you will probally want a larger cam with more lift to maximise the efficincy of the set up... How large will deppend on How the heads flow....
The best thing to do would be to get a set of ported heads from one of our sponser.

Ideal cam choice depends on the turbo kit you plan on running with your truck. If you can be specific about the manifold configuration, the turbo housing size, flange size, A/R ratio, downpipe size, desired rpm range and desired boost level, that would help a bunch.

wait, slow down a minute... some of your sentences are jumbled and confusing...

The 317 heads combustion chamber was designed for a 4.000 inch bore The stock 5.3 is only 3.778 . You would better off having the factory heads re- worked or getting set of already done heads from a sponser. You should speak with some one like Patrick G about putting a specifc package together.

Patrick G is his username and its in red letters. I am more then sure he will take the time to talk with you over the internet and get you pointed in the right direction. I am sure if you explain that your hearing impaired He will understand and try to make sense of your grammer just as I have done.
I will try to find some of the information about the 317 heads on a 5.3L block for you.
Good luck on your project!!!
