Poly Motor mounts for the LS1 installed
Poly Motor mounts for the LS1 installed Well, OK they are not made for an LS1, but they work!
What I got was two Energy suspensions part number 3.1116R. These are made for LT1 cars, they are identicle except for two things. One, they are .3" shorter front to back (taken care of with three washers), and Two the metal protrusions are different. I ended up cutting off two of the metal protrusions and useing the afore mentioned washers, with great results. You will also need 3 bolts and nuts per clamshell to bolt it back together.
Now, I put in the two new mounts yesterday. I was actually surprised to find out the car in now SMOOTHER with them in! There is just a hint of vibration at idle, but my lumpy TR224/224 cam now feels totaly smooth at idle (before it would shake the car). I am not currnetly running a poly tranny mount. But am very impressed with the poly motor mounts sofar. Today I drove the car over a hundred miles, all smooth sailing.
Any way, if Yall have any questions, just shoot them my way.

Re: Poly Motor mounts for the LS1 installed Good Job, Ryan!
I posted a while back about poly motor mounts, and nobody could answer back if they'd done it.
I put poly's in my 79Z, and the difference between 22 year old rubber and fresh poly is AMAZING. And you're right about the noise - I didn't notice any additional either.
I want to put polys in my 98, because I noticed that my stockers are pretty bad looking.
Cool deal. I know what I'm ordering soon. <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />
