robyn said: I too am currious as to why they did not cast the new blocks with a deep skirt and use cross bolted mains

I've wondered the same thing.

Here's a photo I took while visiting DMAX in 2001, showing the deep skirt design used in the Duramax 6600. Side captured main caps would be nice for the 6.5... Jim

Very nice pix of the D Max

I have owned two 427 Ford Side oilers in the 67 vintage and one 427 Cammer of the same erra.

The side bolts have little spacers that are custom ground to fit exactly into a particular spot and are marked so they cant be mixed up. 2R- 2L 3R-3L and so on

I have never seen the breakdown on the D MAX but I ussume they do something similar.
With the crank all buttoned up with a deep skirt and tied into the rail its really tough to break them short of a catastrophic Kaboom.

High nickel iron block thats cast plenty heavy.

OMG we need to get the truck down to the spring shop and get the front end lifted out of the dirt.

I would like to know more about the new block you have pictured though.
I would bet the particulars are pretty well guarded right now too.

That billet dipstick tube is absolutely the cat's meow.......

If that 'girdle' is aluminum, looks like a fancy schmancy spacer to get around the real business at hand, across the mains-webbing inside, maybe with splayed outer bolts to get into the pan rails

(Those angled areas appear to be within the arc of the rod-cap nuts, and would be necessary if that girdle extended inward of the oem pan-rails)

They've plumbed the CDR back around to the oil fill tube, where there's less likely chance to pull raw oil thru at high cfm\Boost pressures - be an excellent arrangement for the current crop of 18:1 hi-po engines, or any performance upgrade, rather than have it plumbed to the street, as is common practice.

That does indeed look like an electric fan clutch setup, and I like the dual t-stat rearrangement to afford more space for IP operations - but, it's prolly only to save money on that long upper rad hose.

But, that's prolly also why they went back to the earlier accessory-mounting package - wouldn't have been room to move the t-stats forward with the late mounting arrangement.

IMO, of course..............

I would really like to get my tools on one of those engines and tear it down all the way.
Fat chance of that happening in this lifetime me thinks

I agree with you GMCTD on the nicks, bumps and bulges on that spacer under the block. There is definately something serious going on there.
That little jewel did not come cheap and is certainly there for a good reason.

Those angled areas very well may house a clearance slot for the rod nuts to swing through. Sure would like to see inside one.

OMG, Robyn did you forget your WD40 and the sun came out? Looks like sunburn to me! Oh, I forgot you found the trick tools................

I would like to see the inside of that motor too. But on my finances it would have to be here on this site.

[Robyn]

Yup me too.
My budgit allows for ebay junk and garage sale goodies.
Oh and dont foget craigs list crap too

My 91 Burb came off craigs list as did the Banks turbo setup and a few other piles of goodies I have stacked up.

As far as the trick tools go. YESSSSSSSSSSSSS.
Once the newness wears off though it will all be old hat and boring accept the smiles They are always good

Good Day!

"Thanks Ron
After I asked the question I went poking around in the User CP and turned it on.

Things are not safe now" Now if we can just get her to hit two spaces between sentences in the same paragraph, instead of "Enter"...

Blessings!

Get real I want it in my truck running!!!!

Back to 6.2, amazing.

But... I like my non-epa friendly CDR vent (does one even need a CDR like this?).

Glad you noticed too, guess I better get ready to polish another one...

Well - dogs like to 'mark' their territory every where they go - don't see much point in doing that with the 6.5, but if you like leaving spots every where over several hundred-k miles, then you prolly won't need the CDR system, with it's added weight and hi-maintenance aggravation, to prevent main-seal leaks, eh?

It has stayed...

The track owner might not appreciate my marking, actually already got in trouble for that once (diesel)

I have the hose from the CDR going under the truck and not in the intake like it was stock. It does not drip on the ground though. It leaves a little coating on the bottom of the truck but it's to prevent rust
