I am interested in installing a Z06 camshaft in my 06 Silverado 5.3 and I was wondering if anybody has done this? Do I need to change the valve springs to the Z06 ones also? Any info would be appreciated. Thanks.

 

It has been done plenty of times. The Valve springs do need to be changed to the ls6 ones. There are better cams out there thought.

 

I agree, the LS6 cam has been put in a 5.3L before, but there are much better choices for it. I'd recomend the Comp Cams XR265HR High Lift with the LS6 valve springs.

 

Awesome cam, runs great and sounds awesome!

 

why is the z06 a bad cam for a 5.3? personally i want something GM enginneered and that is very streetable

 

No one said it was a bad cam, it's just that if you are going through the trouble of putting in a cam/valvesprings in the first place, there are choices that give you a lot more to work with.

 

One of the local boys installed a ZO6 cam and springs in a 05' 5.3L auto truck with long tubes, off road Y pipe, CAI, Magnaflow catback, ASP pulley and John Weeks Tuning. It put 322rwhp & 312rwtq SAE through a set of chrome 24's. You know it'd put down a lot more power without those 24's. Oh and it doesn't have a stall.

 

That cam was designed around a 3100lb car with a close ratio 6 speed trans. Even in the Corvette where you have an extra 21 cubes the LS6 isn't very strong below 4k rpm. Extra weight, wide ratio transmissions, and less cubes make the cam not so great for a truck.

 

i'm thinking of doing the same thing only with the cam out of an ls2 05 gto i heard they were the same any input on this? sorry for hijack.

 

Thats the problem, its not very streetable because the power doesnt come in till way late in the RPM range.

Like Zippy stated, it just wasnt desgined for a big heavy truck.

I5M5, just because it made good peak power doesnt mean its a great cam The LS6 cam just makes its power too high. And that truck isnt going to be very fast in the 1/4 on a stock stall with that setup.

I've had the cam in my 5.3L and wasnt impressed with it.
