how many of you are running an engine girdle???
It really depends what kind of power you are going to be making and what block you are going to be using. I think that for an aluminum motor people probably start to see some movement around the 1000hp level, so it's probably a good idea if that is what you are looking at. On an iron motor ~1200hp is starting to push it without a girdle.
Personally, I think it is cheap insurance on a high dollar motor. If it takes internal stresses off of other parts then it is well worth the money spent...although I wouldn't bother on anything below the 750hp level.
Does it really need it? I have never ran without one on high hp engines, although I'm sure somebody does.

the whole thing ties in better then the other one.
i didnt think mike and steve were running a girtle on their iron block though.
Folks, don't be suprised at the prices...you get what you pay for. When you get something from W2W you can assure that not only is it installed and setup perfectly, but it has also been tested on the dyno. You aren't buying hype...you are buying something that has stood up to real world testing!

Like everything else, this is a case of you get what you pay for...there are reasons that some things are more expensive then others. There aren't a lot of LSx based motors that are making 1200+hp, but from what I have seen most of the ones that are come from W2W.
This conversation probably isn't relevant to a lot of people, since there are only a handful of people on here that will ever come close to 1000hp. For the people that will, my recommendation would be to go with the people that have done it most and repeatably.
The labor to install it in a correct manner is what pushes the cost way up and is one of the reasons we prefer not to sell it as a retail piece. It takes quite a bit of time as well as knowing what to do.

The process is machine the top of the cold rolled steel main caps on a surface grinder to equal all the heights within .0002 on the height of the caps, this is what the girdle will sit on. Then install ARP studs that are made for this girdle(longer length). Install caps and measure from oilpan rail to main caps on 4 corners. Machine oilpan rail of block flat to equalize dimension at all four corners, record dimension of step.
Machine step in girdle to .005 deeper than differential on cap measurment. Install girdle on maincaps (at this point a .005 feeler gage will fit between pan rail and girdle).
install oilpan bolts through girdle to block and torque mains and oilpan bolts.
Align bore main bearing saddles, and hone to factory specs.
Cut o-ring groove in girdle at block interface for .102 buna cord to seal the girdle to lower block surface.
Before final engine assembly install o-ring cord in girdle blockside, lower girdle to pan seals with factory gasket.
Start engine and add BOOST!!!
