LS6 springs with a .558 cam
Im planning on running them on a cam with .558. Being .008 over I wouldnt think would be a problem, but I was wondering if anyone had any hard facts from experience. I dont need to hear from the cyber mechanics that quote mechanoc talk like scripture because of what they have heard.
Thanks.
Thanks.

How about you just buy a damn 918 spring and be happy.
Honestly I have ran a 220/224 553/556 on a 117LSA for over a year with LS6 springs with no problems.
That is damn close to the lift your at and should work fine.

Launching!
Are you serious about all of this "grinding the cam lobes down" business, or just yanking our proverbial cranks? Sounds like a lot of work to save 100 bucks on new springs.
LPE recommends (and provides in their kit) LS6 springs with the GT2-3 cam, which has .581 lift..
It depends on the ramp rate of the lobes as well. We need more info.

Why go to the trouble of getting a cam and knowingly excede the amount of lift the spring was designed to take. Are serious about really grinding lift off a cam. Id tell you not to get a cam and just get a bottle instead but you seem like the kinda person that would blow your **** up. Sorry if I came off as a dick, but the question is crazy from the start.

What do you guys think?

.008 isn't that much to file off, hell you could just put it in a small press an mash it down.
You could always just stretch the spring by .008 to compensate for the extra lift. Just give it a little tug on each end with some pliers.
Are you going to file down the sides of the lobe as well to decrease the ramp angles or maybe you could peen them down with a small hammer and then bondo them smooth.
Please post your results after you are done. I'd like to see some dyno numbers and pictures on how that works for you.
Seriously, it depends on the lobe profile if you can use the LS6 springs. If you are using an agressive profile lik a comp XER or TR lobe, I'd use comp 918 springs. If you are using an older, less agressive lobe you might be able to get by with the LS6 springs. Remember it isn't always the peak lift that will screw your springs, it may be the rate of lift that the springs can't control.
The best advice I can give is to call the cam manufacturer and ask them what springs they recommend...then buy them.
