Nice write up Luna! I printed it out for my near future use!
What would be the downside of using solids vs. the poly? (other than the price of course). It seems the solids would be easier to install, so why dont more people use them?
Can you use poly motor mounts and a poly trans mount without it being too tight?
What about using solid mounts with a poly trans mount? Would that work?

Solids are also a little lighter than the stock clamshell pedestal setup by almost 10 pounds I think.
Also, as far as a tranny mount, as long as the motor mount is harder than the trans mount you will be fine. You don't want rubber motor mounts and a poly trans mount because when you're motor moves more than your trans will you are risking cracking your bellhousing.
I would say solid motor mounts and poly trans mounts are a good idea, I personally still have the rubber trans mount, but its life is probably near the end.

Dude, if you think you want poly mounts, think hard and be sure you really do. They're no cake-walk by any means. He said 20-24 hours all alone. It took my dad, my brother, and me 10 hours to do a clutch swap and the motor mounts.
The clutch was easy. I'm getting too good at pulling my M6.
The mounts were a real bear.

We swapped rod bolts, motor mounts, and replaced the rear diff. cover in a total of about 11 hours on a lift over the weekend. This was the first time any of us had pulled an LS1 oil pan as well.

Great write-up.
Definately not needed, but on a side note: if you can get yourself some used mounts complete with clamshells, you won't break much stride by getting these ready first with your new poly mounts.
If I had to do it again, I would have bought a cheap used set off ebay and got it ready beforehand.

On a side note, doing motor mounts on a stock exhaust car doesnt make much sense.

I have the poly mounts in the clam shell and ready to go. Hopefully I can put it back together tomorrow. I'm beat!![Cry](https://ls1tech.com/forums/images/smilies/LS1Tech/gr_cry.gif)
