Valve Spring Longevity?

[Danno74Z]

Hello All,

I have a question on valve spring longevity. I have a stock 2002LS1 engine and want a little more power from it. I want to go to a relatively mild cam upgrade say to the TR224. I was told that even with a mild cam upgrade, expect to change out the springs and go to hardened push rods. Fine, as I expect to do both anyway. I was also told that even going with a mild cam the new installed springs will only last about 10K-15K and they too will need to be changed out. Are you kidding me? I know tons of folks have changed out cams on this forum and I really want the facts. Question: Replacement valve springs only last 10-15K on a cam upgrade on daily driver not a quarter-mile car?

Thanks,

A mild cam like a 224 with a less aggressive ramp rate should be able to use the correct springs for years and years with no problems. When you start getting into the higher lift/ faster ramp rates is when it here harder on the valve springs and spring pressure should be checked on these bigger higher ramp cams regularly(10,000-12,000 miles) to be sure they are still in specs.

But for your 224 I'd just get a good set of beehive springs and hardened pushrods, assemble, drive and forget about

i i have a 238/248 @ 50 600/605 112lsa cam and i am running dual springs on stock rockers and lifters. titanium lockers on rockers. i currently have just under 45000 mi on the cam settup and it has seen thousands of 6900 rpm revs. and not one recheck. and the car still runs as good as it did when it was built. it has only had one redyno with no retune. as it had only lost 10 rwhp and 12 rwtq. so if done right the springs will be ok.

but i say that with the dual spring system!
