My buddy split his stock 5.0 block 347 with 60mm turbo and it had a girdle, they don't work!!! He has an R-block now, has gone 10.50s with a 60mm turbo and 10lbs of boost, E85 and meth injection, he will be trying 14lbs very soon, and yes he is going for 9s with a Cobra intake.

It seems to me that the blocks that crack with girdles are mostly pretty high up there in horsepower. Like more than you should really try to make on a non boss/dart/351w block anyway. A turbo 347 on e85 & meth? How much power was this making at the crank? 600+?

My point is that the girdles may not make an E block anywhere near as strong as a boss block, but maybe it'll allow another 50hp more than without the girdles? Helping the mains stay in place better and not walking around so much should help something no? I tend to think of the main girdle kind of like sub frame connectors. Tie in all of the pieces along the way and it will make them all a little stronger. The fact that block held up as a 347 with a turbo on e85 & meth at all is pretty amazing to me.

Not saying you're wrong, just throwing out some points that I thought made sense.

Mexican blocks have a bit more main webbing and blind main bolt holes along with wider main caps, so they have been proven to more HP, still dont compare to a 4 bolt block but they are nothing to look over.

I don't think it was making anything close to 600hp when it had the stock block, he will be lucky to get 650HP maximum with the new motor with that very small 60mm turbo.

I've said all along..only thing those girdles are for is to make sure you have 1 piece of metal to remove instead of 2 when the thing splits....

I thought a lot of these problems with the blocks cracking down the center had to do with high RPM and a decent amount of HP 500ish?

Sadly this is the fate for any stock block 5.0 if you want to go balls to the walls!

Of course not everyone has $1500+ to spend on a 4 bolt main block

I thought girdles just helped with main cap walk? Not preventing the block from spiltting. I've split a block with one also. 331 Trick flow heads and a 200 shot.

I recall reading somewhere that a main cap girdle will, in most cases, at least save your rotating assembly when a block fails.

Anyone have info on that?

I guess you are buying used blocks. Because you ain't getting a iron eagle block for $1500.. More like $2,400+.

I laugh when I have people ask me about girdles. While a main girdle will help with walk. That is about all it's good for. It will not keep any thing together if you start detonating the motor.

Yea I was thinking used blocks... I would never put $2400 down for a bare block... If I really wanted something nice i would just get a coyote 5.0 for another $4k brand new from ford...

sure..if you really wanted..lol... love when people say this...but it never happens

Lol wait..some of you really thought a STOCK 2 BOLT main 302 would NOT split or crack with just a main girdle and 500+ HP

Cafords ftw

How do you know when the block split happens? Looks like this one is cracked, but might still run.

I did 531rwhp through a C4 with a stock block and stayed together but I knew it was on borrowed time

I was always under the impression that a girdle would only keep everything together when it split , therefore saving parts from destruction, at no point did i ever think slapping a girdle on a stock 5.0 block would help it be stronger , 5.0 stock block is a stock block no way around that . Girdle is more of a saftey measure i would think

Never understood why people never just buy aftermarket blocks before sink money into the stock block.
