Looks like everyone is using the same girdle. I would like to see the W2W girdle, since I am more interested in providing my customer with a girdle that ties the mains in to the block directly. The girdles work quite well especially on the GN, since their weakness is in the mains and not the lifter valley like the Fords. Girdles on Fords are pretty much pointless to me, since that is not their real weakness. The one good thing about a girdle on the Ford's is, when they do crack in half at least it holds the block together from scattering...lol

It seems to me that the real advantage of the girdle would be to prevent block distortion, not cap walk, although it might help here too. One thing that might make a bit of differance would be to go with billet caps and studded mains including replacing the smallish side bolts with oversized studs thereby tying each cap individually to the block better and using the girdle simply to tie all the caps to one another. This would seem to help both block distortion AND cap walk ? Just a thought

Yes that is what I was told.
I would agree that there are a number of ways to make stronger girdles, but at what expence is all I am saying and the DM girdle can be used with billet mains I know Thunders will work not sure about everyone elses Billet main caps. Good luck with the setup Big Mike sounds like you are going to be running good.

i think the ohio boys mains did some walking when they were back on an aluminum block, before they switched to a w2w iron block
harlan of all people should be able to tell you how his aluminum block held up, think that one did ok cause didnt he put it in his truck?
not sure who made more passes but steve made quite a few with that aluminum block, when your at that level, its just a matter of time before things start to wear out.

Our girdle connects the mains to the block side skirts. We believe this offers the greatest block support to aid in main's stability in high output engines.
The side of the plate that touches the block has a o-ring groove for positive sealing. The lower side of the plate uses the standard gasket, although the hardware needs to be longer to make up for the plates thickness.
This system is only used in our most extreme high load engines.
There are three engines using them now.
Ohio boys racing. On the "Formula". Best ET 8.12 best MPH 178. dyno 1550hp
Mark, Con and Vic. On the Ute. Best ET 7.4x@ 18x. dyno 1570hp
My personal 5.7- In "Casper". Best ET 7.52@ 187. Dyno 1697hp
Scott Allen 6.6- Best ET "coming soon" Dyno "4 digits"

Kurt is that stainless or aluminum? Looks very nice I like the oring grove alot good sealing and preplanning on your part. I stated above that I believe that one that attachess to the skirts would be stronger. I Just don't think that DM one is going to be that far behind on cappabilities. How much further down does the oil pan come down did you have to modify the K-member at all? Is there a special procedure you are using on the line bores and then assembly etc...
Aluminum girdle. The pan moves down about .600. The cars we have used these on had tube type k members. All but Scotts had dry sump pans.
Scott does your k member clear?
We install the girdle in place, then align hone for final fit.

Wheel to Wheel Powertrain is where I work.
We do not sell just the girdle as it is hard to install. We will install it on your block if you send it in. Call Billy @ 248-589-1190 for pricing.

Could somebody describe what main cap walk looks like? I tore down a used motor I bought (AL block) yesterday a noticed that the area where the main caps contact the block are discolored.
Thanks for your help!
