Being new to the C5 Z06, is it normal for the shifter to rock left and right a bit as you accelerate and decelerate in gear? I can only picture the drivetrain torquing back and forth but not sure what is "Normal" or something to be concerned with.
Car has 70k miles.

Define 'a bit'? Is it every gear or just one? What about coasting/braking with the clutch pedal in? Any sounds?
Some vibration is normal and the C5Z is a harsh/rough ride compared to something cushy and modern but the shifter doesn't strike me as vibrating any more than my other cars did. Could be the shifter is a bit mushy from being leaned on or used and abused (mine is pretty low miles but doesn't feel that loose). Otherwise could be anything that causes the car/drive train to shake under accel, a motor mount could have dry rotted away, you could need a new harmonic balancer (a very common issue) or maybe it's a torque tube issue (though I think that usually manifests as a scraping sound)... Try to rule out suspension stuff too.

Really not vibration. As I am driving, if I gently let off the accelerator and gently accelerate, the shifter rocks right and left a bit, you can feel it in your hand. *maybe* 1/8-1/4" total left right movement? To me that would mean the entire drive train from the engine back. It might be normal, I am not sure.
I had a similar issue. In my case it was worn motor mounts.
At the time I tore the engine down to this in preparation for heads & cam.
New motor mounts was one of many "while you're in there" moments.........

Hmm, I will have to take a look at that, if everyone concurs there should be no left right movement of the shifter when accelerating or decelerating even gently.
At 70k miles, someone must have really romped on it if that's the case.
Any one do a motor mount swap out? Not too difficult? Urethane mounts or OEM?
I went with Hinson mounts. I was installing headers at the same time and had the torque tube out for a clutch swap which allowed me to tilt the motor back and forth a bit to get the mounts in and out.
Even with the headers out, its tight down there. I ended up removing the engine mount brackets from the block, then removing the mounts. I then dropped in the new mounts and then installed the brackets back onto the block.
If you go with a stiffer engine mount, you should consider “matching” those with a stiffer differential mount for proper balance.
I have the AMT mounts and a HPI differential mount and there is no drive train movement.
With this setup there is some moderate vibration/harshness coming off idle to about 1800rpm, but at cruise its no different than the stock rubber mounts.

Thanks,
Jumped on YouTube to get an idea what it takes. Not trivial but not bad. However, one guy pulls the intake off and another engine cradle from below. I have a friend who has an All Data subscription, will find out exactly how its supposed to be done....

Marty - you likely have blown motor mounts. The diff mount also gets pretty floppy with age, and with the addition of potentially blown motor mounts the diff mount could exacerbate the problem. We offer a 10% discount on our motor and diff mounts when purchased together if you decide to go that route. Best of luck and please let me know if I can be of service!

I did mine at the same time I did my headers and did it with the intake manifold off so I had lots of room, and if i did it again I would probably just take the headers off again and not mess with the cradle.

How hard was it? What tools do you need? I plan on doing headers at some point in the next year or so, would you recommend doing the mounts at the same time as an upgrade?

But taking the intake manifold off is a must right? Might as well replaces the oil pressure sender at the same time...

If your going to do headers, it would be the perfect time to do the mounts, with the manifolds/headers out of the way you have a ton of room and it makes the job very easy.

You might be able to get away with not taking the manifold off, as you don't have to lift the motor that much but you run the risk of cracking the intake/firewall.
The intake manifold is easy enough to take off by itself. Me personally, I would just wait till it failed and then deal with it.
