Topic: Best Bolt On's for performance?

The specs you show are correct with the exception that it's 218, not 219.

As far as I know, it's a direct bolt-in proposition into the Gen3 motors. Don't take my word for it, though, make sure to verify this with someone who is certain regarding fit.

This would make a good cam for you and you could probably tune this one with your Predator.

Off to do my research on compatibility of this cam--Thanks Joe!!  Sent him a PM.

This thread at LS1 almost says that it will fit, but my question is, is this cam as aggressive as I was looking to go with?

I'm pretty sure the lobe ramp rate won't be as aggressive as the Comp XR lobes and you have a 204* duration on the intake instead of a 212*. My guess is that this cam would be pretty comparable to the low lift 212/218 cam. It's just a half-a$$ed educated guess on my part but I doubt you'd give up more than 10 hp.

In my mind you just have to answer the question to yourself if saving somewhere around $150 outweighs the benefits of getting exactly the cam you currently think you want.

Key phrase is "the cam you currently think you want"!  It's all good!  I do like the price!

OK, I'm going to ask a dumb question here only because I know most of the folks and I don't give a rats  what anybody thinks!!     I've done my fair share of work on the older Chevy small blocks but nothing to speak of on the newer LS1 version.  What do I have in my 02?  LS1, LS2, etc???????

Your 5.3L is based on the LS1 design.  The LS1 has about 25 more cubic inches and an aluminum block - just about all of the other differences are very minor.  The LS1, LS6, 4.8L and 5.3L without cylinder deactivation are considered the Chevy 3rd generation small block, or Gen III.  Parts are generally interchangeable in these engines, although of course there are cylinder diameter and stroke differences to accommodate the different displacements.  The LS6 was the souped up version with the hottest cam and some fairly exotic valves.

So what are your thoughts/concerns about putting a 2004 Z06 (LS6) cam in my AV?  Thanks!
