What would you still consider a 6.5?

A simple question, what would you guys still consider a 6.5l diesel if one were built to the nines?

As in the ONLY stock parts are the block, accessories, and small odds and ends like that. Assuming the bore and stroke stay the same of course (save for a .020" possibly. Thanks for your input.

Let me give you a slight bit more insight. Direct injection, common rail 6.5l diesel.

6.5 Detroit Maxx :thumbsup: yup I'd buy into that just has a better sounding ring in a GM/Chevy truck than that ole designed in Japan Isuzu D-Max ):h

That would be cool! but it would be a lot of work. Yes?

But very way cool; a 6.5 on STEROIDS, more power arh-arh-arh

I will never disagree with that.

 

[chevyinlinesix]

Less work than I was going to do with the engine before, and it will cost less overall, which is a big plus.

What about heads?

 

[mattthebrat]

A motor's a motor, Scheid's Cummins pulling truck uses 4 OEM parts on the whole truck, and it still has Dodge and Cummins stickers.

 

[Matt Bachand]

Super cool idea... keep us posted as always!

What about heads?

Mr. Detroit and Mrs. Duramax are going to have a roll in the hay ):h

 

[ak diesel driver]

So I'm assuming 6.5 heads with duramax hardware

 

[randomid25]

Nope, Think 6.5 Bottom end with Dmax top end, Fuel system, Probably a modded 6.5 timing cover to drive a cp3. I might be a little bit off but not much. We were talking about this the other day.

 

[ak diesel driver]

So Dmax heads will bolt on a 6.5?

 

[6.5coalroller]

Would the 6.5 bottom end hold up to that? I gotta admit that would be pretty sweet tho.

 

[chevyinlinesix]

So Dmax heads will bolt on a 6.5?

From what I see, they are close enough. The block deck will be plugged and new holes drilled into it.

As for the bottom end, mine will be stronger than a Dmax bottom end. Yes, it is a lot of work, and yes I could use a P400 block, but I'd have to buy a complete engine to get the P400, and it seems wasteful to buy a whole new engine just to tear it down and change everything. Once I get my hands on a set of head gaskets, I'll be able to verify a few other things as well, but all looks good so far.

 

[ak diesel driver]

New holes drilled for headbolts or water passages?

 

[chevyinlinesix]

Some new head bolts (will be studs) some new water passages.

From what I see, they are close enough......

Now this I gotta see. :skep:

Ya know the more I think about this the more I don't think I would consider this a 6.5 anymore. Part of what makes it a 6.5 is the IDI part of it. If your going to all the trouble to modify the block to put Dmax heads on it why not just use a dmax?
