im sure i missed some other stuff but lets jus say it was impressive for what he had in his sig'
will using a smaller cam like the 02 Z06 cam quiet down engine bay valvetrain noise? (ie rocker arm noise) i believe i got yella terra rocker arms are certain rocker arms noisier than others?
mine is like 222/218 560/560 116

P.S. I running a ATI P1SC w/7 lbs. of boost on a bone-stock engine.

When I bought mine from Lingenfelter I got it with LS6 springs. That's it as far as valvetrain upgrades. But I also don't have 100,000 miles either, only 27,000. I asked Lingenfelter about it and they said it should be good up to 6300 RPM. We'll see if I keep the GT2-3 after my turbo though. I hear reverse split is the way to go in that scenario...
On Thunders site, it says the cam has a smaller base circle, which means you should need a .050 longer pushrod....
LS6 Camshaft - 204/218 .551/.541 117.5 LSA Please note that this cam has approximately a 0.050" smaller base circle than a stock LS1 camshaft. This smaller base circle will require longer pushrods for applications with stock length valves and no milling for the head surface.

MECHAM, valvetrain is just as quiet as stock, only thing I can hear on mine is a little forged piston rattle and the injectors

Hey everyone, just a queston. If you went with the Z06 cam, but upgraded the rocker arms to a higher ratio, would that not make the cam more halthy? For instance, on a 406 (400 small block 00.30 over) the cam was rated for 1.5 rockers, but it was common knowledge if you got 1.6 or 1.7s it would increase the size of the cam. I believe stock rockers are 1.7, so he mentioned he has yellow aftermarkets. If they have a bigger ratio, would the cam size increase by more? For instance, .551 lift would go up to around .563 if I am right, and the duration would go up a little too.

Should be about the same for an LS1 (1.7 to 1.8). You also pick up a couple degrees of duration. It can be a good way to pick up a little extra power without hurting driveability.

question for you all , i found a ls6 cam from gm performance but the specs are opposite of what this thread started with
218 intake 204 exhaust @.050 550/550 117.5 lsa which cam is the correct ls6 cam????
218 intake 204 exhaust @.050 550/550 117.5 lsa which cam is the correct ls6 cam????
I believe that is the 01' Z06 Cam. The 02' - 04's is the cam Im dealing with, that carry the specs posted in my first post. Correct me if Im wrong but I think that is right...

Not a considerable amount with a hydraulic cam.

i just went to gm performance on line and looked up a 2002 ls6 cam and its specs are 204 intake 218 exhaust @.050 550/550 117.5 lsa -- sorry about the confusion - summit must have it printed backwards. my bad
