6.5 Girdle

[Shikaroka]

I am certainly interested in this.
I hope anyone that gets more information on these will post it up for all to see. I am curious to know the cost of these things, if he can build more.

If I am contacted regarding the Girdle and there is information to share, I will.

I'm using 12.9 cap screws and have installed one set on Blazin when we replaced the engine.(see post, oil in coolant) in seems to be going well and we didn't do any modifcations to the pan. It is made of 3/4" steel. When doing a search for girdles on e-bay they all seemed to be alum., am I not getting something?

These are pictures of the prototype girdles. They fit on an otherwise unmodified motor, including the pan. The final version still does, but is 3/4 inch thick instead of 5/8 inch. All five mains are covered. Unfortunately, we don't have pictures of the 3/4 inch version because it is 1000 miles into use on the truck, and pictures weren't a priority when the engine was prepared. It seems to work fine. Of course, it takes much longer than 1000 miles to test a girdle.

How will that support the caps if the girdle is not tied into the block?

The end caps 1 and 5 are very strong as they are fastened to the ends of the block where there is massive amounts of material and the girdle bars tie the whole lot together.
The best way of course is to do the complete girdle with the cross bolts and anchor everything along the way.

This simple tie bar is still a very worthwhile addition to any 6.5.

One thing that is absolutely a step in the right direction is to lightly chamfer the bolt holes in the block on all the mains especially the center ones.
The ragged sharp edges in the block are a perfect send off to getting cracks started down the outer bolt holes..

All really great stuff in this thread. Good tech and a step in the right direction.

In all the pictures posted in the thread (oil in the coolant) all the cracks seen to follow corners in the machine work ie. the piston bore. Robin is rigth that a sharp corner will not stand the pressure of a radius corner. The stress is spread over a larger area. All we can do is try to lessen the damage by rounding and bracing. Blazin has some personal value due to time spent with my son. So it is worth it to me to try. Question: Is the pattern on the mains the same on a 6.2l and a 6.5l?

Is the girdle still doing fine?

Would it be possible to get your drawing for the girdle??

[82blazer]

The girdle is still there and seems ok. This engine seems quieter but I never heard it before it was put into [I]Blazin[I], we are probably around 3000 miles and have done some towing with it. It is driven almost every day but normally not far my son uses it to go to school. I'll need to locate my drawing and get back with you.

That would be great
