Starting off on the right foot

[oldestof11]

the way the injector enters the head is the reason for bowl placement. 12vs at an angle, the 24v head is centered.

The 12v head also needs some special attention acoolant passages don't line up. Get a cr head gasket and hold it over the 12v gasket. You will see.

Why wouldn't be able to run a 12valve piston?

Bore size is the biggest obstacle, plus the fact there are no OEM 12 valve pistons for an ISB/D 6.7.

Sure was looking forward to basically having a stroked motor in a first gen that was capable of lighting big turbos. Back to the drawing bored I reckon.

Why not just use the 6.7 crank

[rabbit86_06]

What I've read it's not capable of just using crank in 5.9 block.

[RCCUMMINS89]

I haven't looked into it, but I've heard of people that claim they have done it. It'll take block machining but, ?

[Mark Nixon]

I've laid a 5.9 crank in a 6.7 block with a 24 valve cam to check gear meshing and double check that a VE timing case clears correctly-which it does- and i didn't notice that the crank journals were spaced any differently.
The main and rod bearings are the same diameters.

The biggest differences I saw was the crank gear and the locator dowel on the nose of the crank was different somehow.
But there again, you'll at least need machine work to the pistons, or custom pistons.

They share the same connecting rod length.

I'm almost positive I've heard of guys running a "stroked 5.9"......need custom pistons though.

Diesel power mag had an article on a sled puller labeled lethal injection or something or rather. 6.7 rotating assembly/24valve head/5.9 block.

Okay, you lit that fire.
I don't read magazines unless they have great looking ladies, Ts&Ts, with full frontal exposure.
Anything else is window dressing for advertising and catering to the few who can afford that overrated BS.

Not to mention that, in my past experience, most Magazine editors might as well be one of those fake wrestling announcers, all blow and no substance, just pump up some BS for ratings.

Since we're on the subject...

I happily subscribe to Diesel Power and have done so for years. I take everyting with a grain of salt though. Just because some magazine editor, key board racer, or blow hard in real life says something because they have X amount of years of experience "in the industry" doesn't amount to a hill of beans in my court until a figure it out, do it, or see for myself.

Do you seriously expect a puller to cough up his secrets? To a magazine that hundreds of thousands will read at some time or another? No. A 6.7L rotating assembly, 24valve head, and 5.9L block are all vauge descriptions. Who knows what machining went on to get those to fit together.

I agree,but it could/did/can be done. Just because someone lacked money/expertise to do it doesn't mean one should look down their nose at it and call bs. After all things are considered who are we to set an say it can't be done or It would be easier to have our peckers nailed to a 2x4.

You need to remember that at one time someone also said that 700HP couldn't be had out of a ve pump to.......guess they were wrong. Now add drugs and see 1k HP as a reality.

Wow, what a strong opinion about this. Playboy not publish a dirty short story for you or something?

[RCCUMMINS89]

LOL...........


I'm told on a daily basis that 400hp ABSOLUTELY CAN'T be had out of a ve. But then again, I talk to "big name" places daily. Most of their "sales techs" are 20-25 year old kids who don't know a thing about anything except what tuners to stack and who they can send $2500 to to make their p pump piss fuel out the tail pipe.
