I bet all them guirdles everyone runs on their rocker arms arent doing $hit either.

And putting a girdle on makes the main caps stronger as its still a stock grey cast main cap WOW I get it add a girdle and presto the caps are stronger and the webbing stronger HMMMMMMMM I have a hard time believing that.
Is that like putting new rod bolts in an old set of rods the rods are now stronger not hardly its just better hardware in an old set of rods!!

So sure, reinforcing a poorly designed item is necessary, hence why we run girdles on the valve train. Properly designed valve train, such as shaft rockers don't require additional assistance.
So, in the end, it all comes down to the part you're talking about.
I've seen quite a few high end motors, Chevy's, Olds, Pontiac, Hemis, BBF, etc, and the only thing I've ever seen that needed a lower end girdle was a SBF. Kind of indicates that in a high horsepower setting, that block is the only one that needs additional strength.
Will adding a girdle to your BBC hurt? Probably not, so long as it's in place when you line hone it. If it's installed after the fact, and tweaks the studs, then you may be doing just as much harm as help.

I wasn't implying that a BBC was weak I just think by putting on a guirdle I'm making already strong block stronger. I also know that "KENNY" at CNCwhatever is in the business of selling and installing billet main caps so sure he doesn't recomend using them he wants to sell you parts and machine shop services.
I'm wasn't trying to sell anyone on the idea of using a main stud guirdle, I was merely replying to a post.
I bought mine because they "DO" strengthen and "WILL" make anything stronger and more rigid which is why the inheritly weak sbf fords guys use them in the first place.
I don't have money falling out of my butt like some folks do on here
to spend on fancy 4 bolt splayed main cap conversions I did the best with what I had. I bought mine roughly for what it cost to buy a set of arp studs so yeah I bought the guirdle which came w/ studs and no I didn't have to mill the main caps down to make it fit and yes they clear my H beams rods.
Have a nice weekend, Charles

Putting a girdle on top of main caps does not make them stronger as they still will flex between the studs as we have seen a 2 bolt main block with a 3.750 crank and a girdle on it and the caps still walked in the registers.
At least with billet caps it make the lower end stronger and act as more of a girdle then bolting a peice of aluminum to the top of the caps.
If girdles was the answer it would sure save ma a lot of time in the machine shop!!!
