Hmm, I have seen them for the older SB motors but not the GenIII stuff. Good if you are running major HP, boost, or nitrous, especially on the aluminum alloys.
Not sure but looks like you need some different main bolts plus there could be issues with the windage tray, too.

Yes I know what you are going to say.
But this is JZ'sTA your talking to, I tried a search and found this.

Didn't help much.
I will try again and see if I find some different results.

The idea behind the girdle is sound. The gen 3 C5R even showed signs of problems when you exceed 1000hp. We make a girdle system for high hp use. It requires many changes including main studs that are made by ARP for use on our girdle. Ours also spaces the pan down around .600 at the rails.
The bottom line is most people don't need them, but some people that do need them don't know it yet.

Looks like something that some of the more extreme motors might benefit from, but for the cost of the unit itself plus the custom studs, probably not something that the majority of us need to worry about. I would worry more about oil leaks with the thing than losing my bottom end without the thing.

Does that girddle have an impact on the location of the bolts that go 90 degrees into the main caps for the crankshaft?
All the other girdles that I have seen in magazines and such are constructed very differently....they are constructed so the bottoms of the main caps are tied together ...this one looks like it follows the outline of the oil pan, is installed under the caps and moves the caps away from the block by an amount equal to the thickness of the girdle....
Totally weird design....it looks like it would require differnt caps

Robert - Here is a better picture than the one you were looking at evidently. 
It is on the bottom of the mains but, does not interfere with the oil pan rails.
I think a stronger design would be like the one that Kurt mentioned in his post that they make that ties the oil pan rails and mains together.

you do not need the girdle to extend to to oil pan rails, the caps are bolted to the block (also you will not run the risk of oil leaks,due to the diffrent rate of expantion due to dissimilar metals), the girdle fits the stock oil pan and windage tray , you do need custom arp bolts, the girdle will reduce windage and dramaticlly reduce vibration so the engine will not shake it self apart also it ties in all the main caps , I am getting the patend on this , it works and works well.

The girdles I have seen are much thicker than this one,,,,, like about one inch thick!
My in itial reaction is that this girdle looks very thin and may not provide much extra reinforcement....
Any thoughts on the thickness guys?

Our girdle is .750 thick at the mains and about .550 at the oilpan rails. Ours is made of aluminum, the one from 274 is SS so could be much thinner and still have great holding power.
I have one of our girdles on a stock cap that will see some boost before the end of the summer, after dyno we will disassemble and inspect mains.
