I found some LS6 Valve springs for $55 NIB.
Would this help me out?
My truck has 151k miles on the LM7.
When i put the STS on, would i benefit from these LS6 Springs?
Stock cam for now.

How long would it take to change'em out?

 

I can't see it doing anything for you unless you change the cam too.

Spring swap isn't too bad if you know what you're doing. I can't remember how long mine took in the truck though. The last two I have done were out of the truck so they went fast.

 

They can help keep you from valve float if you plan on going to 15-18psi of boost, and 6k+ rpm but other wise there really not too necessary for a stock cam, but it is nice to all ready have them for when you do decide to do a cam swap. That's about the price SDPC sell them for BTW.

 

Im only goin to run 6psi. and probably wont be revving past 6k. Depends on where the power is goin to be at.

 

If your gonna do a turbo and all that, buy the springs and buy a used 2001 LS6 cam from lingenfelter performance. They'll sell you both for 100 bucks.
LS6 cam w/ a turbo woo hoo sounds sweet.

 

If you buy the LS6 cam it should move your power band up. What would I do? I would drop in the LS6 cam & springs. This should move your power up to about 5800. Get a mild port and polish on the heads but have them clean up and maybe enlarge the combustion chambers, when you bolt the heads back on go w/ a thicker gasket, the chamber work and thicker gasket will lower your compression just a bit. You'll need to move up to the next injector size after that and maybe a fuel pump or regulator will be needed.

That's a sweet combo. The reason for the head work and all is it will let the turbo work better, you should be able to add more boost too that also. I'm not sure but I think a stock block should handle about 10 psi ask around.
Another idea, if it don't make the valves hit the pistons I think some rockers on the exaust side should help too. Ask around and ask lingenfelter if you buy a cam thru them, they are turbo wizards.

Even sweeter if you add a LS6 intake to that.

Most of all match all your components, looks like your shooting for power in the 2,000-6,000 range, buy all your mods based on that.

 

....but for now, based on what you're doing (STS @ 6 psi on stock cam), the springs aren't going to do anything for you.

I've also never heard of anyone just changing exhaust rockers? I don't even think you can.....all of the valve events should be ground into the cam, not adjusted by mismatching rockers.

 

just some info on that ls6 cam post. The gt2-3 is a ls6 cam on steriods. lol

Im with thunder on the springs tho.

 

Thanks guys.... just wondering... but she is goin to stay stock... ive got a Walbro 255 intank. and 44# injectors on the way.. maybe next year she will get a cam?
