Is this cam worth the swap? do i need a tune? it would come with springs and pushrods so is that all i need? motor is otherwise stock. the cam is from an 02 Z06 what kind of gains can i expect?

 

I am doing the exact same thing as you are. I have a bone stock 5.3 and I am installing a 02 LS6 cam(150 for cam, springs, and pushrods, could not pass it up!)

According to an engine dyno test performed by Will Handzel(author of Chevy LS1/LS6 V8's) the LS6 cam showed 11 ftlbs of torque, and 39 HP increase at the crank on a stock engine. Keep in mind, this engine had headers for the test, that will make a difference. The cam also made the HP increase at 5800 RPM, up from the baseline of 5200 rpm stock peak power.

I would put in the 2004 Z06 cam. I would put in the springs if you have time.

If you do that then you will be on par with a LS1 at least. The stock LS1 program will work fine but be a tad rich. You could plug in the stock LS1 computer with O2 sensors and never worry about it.

 

if you click on the "Performance Trucks" tab at the top of this page and go to the "GM Internal" section and do a search, there is probably about 15-20 threads about putting LS6 cams in 5.3 trucks.
i'm not trying to be short with you, but there is already more information there than you could get in this forum.

 

thanks for the info guys. I tried to search but was timed out each time I tried so I figured I could ask anyway.
