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.

Nope doesn't look like it will help the rest of the block from cracking

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.

Brandon,
Look at the main webbing where the block cracked.
No girdles of any sort are going to prevent that. You simply cant put meat where it wasnt cast.
Since I know what you are getting at and you are on the fence about getting a 4 bolt block to compliment your twin incon kit.....Imma say this...DO IT!!
Fran or his brother got lucky with this one, it didnt hurt anything else.
TURBO50 OUT!!

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 ![[Frown]](frown.gif)

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...

Even then..... It will only handle..... 600 or so RW..... If you want a good Coyote..... Get an Aluminator or...... A L&M...... But most people..... Will still say that..... Is too much money.......

Broke mine with both lower and valley girdles. Made just over 400 NA. Got greedy and decided to squeeze a small shot and after 4 passes it was DONE....

I feel like a very meticulous balance job would be the best bet in terms of longevity for the block. No?

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