not to start a fight but u will get valve float at 7000-7500 these are factory valve springs not racing springs. just because a tach says something doesn't mean i will go that high. also the cam is not designated for high rpm you will actually loose power if u go higher. take a look at a stock dyno graph you can see the tq curve drop rapidly. the rev limiter is there for a reason don't mess with it unless u have properly built the engine for it. i say this not from reading books. i have built ls1/ls6 and are very familiar with the lsx family. not to mention they are not that balanced from the factory to run above 7500 rpm. again no to start a fight just some information for thought.

Good luck getting them to cover a warranty that is NULL and VOID from moving the rev limiter, and getting caught street racing.

Anyone know if the V-6 has a rpm limit? I was told it did not.

but all tach's lag. I have hit the rev limiter a few times and the tach was a few hundred rpm's behind.

Nunzi Romano used to say rev limiters were for pussies but I am glad I have one.

On another note if GM designed the Camaro to be a drag car it would have a solid axle..........

Like you said GM opted to set the RPM limiter for durability, the LS3 engines are tuned for 100,000+ reliable miles from the factory. If you want to tune it for racing I think that's great but that's not what the warranty is for.
