Too much valve spring
Too much valve spring Seeing that the ls platform is a roller setup
If your running say a high 5 hundred lift cam with a spring rated at .800 lift.
Is too much a bad thing or a good thing???..
Please advise

its really a good thing.
the more lift you run, the better spring you will want. if that spring can support up to .650 lift, and you run .600 then you can probably make those springs last a little longer.
Running a lot of lift, close to maxing out your springs are a bad things, and shortens the life of them as well. I'd reccomend a good dual spring good for .650 Not many people run lift in excess of .640

No, but where did you find a spring rated for .800 lift?
Installed height, diameter, open seat pressure, lots of other factors in determining a good spring for yoir combo.

You want to run a spring close to coil bind, and need enough seat and open pressure (whomever you buy a cam from should be able to provide with out much open and closed pressures are needed). More than what is necessary will put too much pressure on the cam and lifters; especially with hydraulic lifters.

Air con pwr steering windows locks hydro boost brakes ls2 dbw standalone harness
It had a solid lift cam 406 350 w/brake 4.33 gear
Going to run cam above 93 octane cam "allegedly "
Cai long tubes would be pretty nice car. My first ls endeavor

Yes that is too much spring for your application! Will it work yes, but at the cost of the rest of your valvetrain. Just pick up a set of PAC Pro LS 1500. They will suite your combo well and you will reduce valvetrain weight as well. In turn will make it easier to control the valve with less spring pressure.

bigger is not always better. greater seat pressure on a small lift cam will have the valve giving the valve seat/lifters/rockers/pushords a very good workout.
there are a lot of people who over spring their heads.

I don't think my question was vague at all. Based on people's responses.
Found out what I needed to know.
Thank you
Opinions are like... Well you know the rest.
Human nature to say what you said when dude called you out.

Been there done that doing heads/cam/spring/stalls etc etc
I had a 228R cam (228/228 .588/.588 112lsa) I had a choice of running either beehive springs, good to .600 lift OR the doubles which are good to .650 lift. The 228R runs .588 on both intake and exhaust. Given that both spring packages are very similar, and both seat pressure heigh diameter etc. were within tolerance, I went with the duals since they would leave a bit more life in my springs vs the .600 single. Hence the reason I gave you the advice I did. Take it with a grain of salt, theres a lot that goes into choosing the right setup.
I'd still like to know where you found a spring good for .800 lift that was for hydraulic roller cams though!
