The springs have been in my motor now for around 3 years. Granted its been 80% street car, its still ran hard. My cam has a .610 lift and i run .630 dual spring patriots. You guys ever change them out at a certain interval?

With that kind of lift I'd change them annually if you track the car a bunch or at least every 10k miles.

My '08 C6 has a number of bolt ons but I haven't changed my cam or springs in my heads. I have gotten to > than 410 Hps to the rear. What should a guy like me do? I run 7 to 10 HPDE envents per year w/ a few local clubs here in the Bay Area. The fact that I still have the same springs that came with the original equipment, but should I be concerned about not servicing these? Don't my springs start to give out? Good timing on my part as I have been thinking about this.

I'd leave it alone if you haven't changed the cam. Aftermarket cams have more aggressive lobe profiles that open/close the valve faster and more lift which opens it farther. This puts more stress on the spring which is why you upgrade the springs when you change a cam.

Running 7-10 HPDEs a year I'd probably swap the springs at 100k miles on a car with stock bits. Building my current race car I swapped the OEM springs out because the car had 119k miles on it. I've put about 3000 track miles on it in 1.5 years. Haven't really thought about when I'd want to change them since I'm running a stock cam.

On my old Z06 I had a G5-X2 cam which is a 232/240 .595/.608 114 cam. I used comp 921 springs and changed them once they had 15k miles on them.

Just my $0.02

Instead of guessing, why don't you just have them checked? You don't have to do all of them.

Easy to do low cost maintenance. Change them now!

With that much time, I would change them right now.

While you have them out, put them on a tester and see what they are at installed and open.

I would start yourself on some sort of parts schedule for the car, and rate them on the hours ran on track. We will generally do springs on the race cars every 30-35 hrs run time, like Jim said it's cheap insurance. Springs are easier to change than a valve in the piston.

Really depends on the cam, the lobe profile, and the quality of springs what you are going to have to do with the springs on it.

Even on a stock car that is heavily track'd I would do springs at the very min. every 2 seasons. To cheap and easy not to.

^ Was waiting for your reply... curious what your opinion was going to be on a stock cam'd car. 2 seasons is probably a good idea
