6.5 to vm638

[Cumminsfever]

Engine is a bit longer than I remembered. Gonna need to slide trans back about 2 inches. Slowly it will come together!!

All of the VM engines with modular heads had this head cracking issue when I looked into them. It was just the nature of the beast as one would say. I believe it had to do with how the coolant circulated(or lack there of) from the individual cylinder heads, and the loss of material between them to absorb and deal with heat. Another one of them great designs in theory, but in reality didn't pan out.

He is pulling the 6.5 out because of cracked head...... The VM has much more torque and is built much better. Looks like a Cummins on the inside.

Going from 1 unreliable engine to another... Lol!

I realize he is replacing teh 6.5 with this engine, but the VM engines with individual cylinder heads are known for cracking heads(he even says this earlier in this thread). And the head cracking issue is why I ruled them out for mine.

Yo.. What's the status of this bad boy.. ??

 

[Cumminsfever]

Complications of the accessory mounting brackets. While I'm making stuff, going ahead and putting a/c compressor on too. Fun fun!

While I was glancing at some pics of this engine, it looked a lil long and tall... Is there gonna be any interference problems withe the front crossmember or front differential..?

 

[Cumminsfever]

No height issues mike. It isn't that tall. It is long. Gotta slide the trans back about 2 inches... so I can use my dodge fan.
clears front axle nicely. Power steering pump was hitting my steering gearbox. Figger if I'm doin this, may as well do it rite!

Good.. glad to hear that.

This is why it takes cumminsfever so long to do anything,this is his "secret squirrel " work station.:rof:

The cracking could also be due to all the heat cycles put on from previous application. Seems like new heads don't have as much issues.

Dont look at my work until its finished! :secret:

it looks like my tool chest...:hihi: beat you to it Bill

 

[Cumminsfever]

Gotta somehow keep the good stuff from getting seen before it is done

 

[Cumminsfever]

So, I got to thinking about my cast iron flywheel, and how thin it got when we machined it. Less than a 1/4 inch thick. Got told by a few people that have experience that it will shatter. I need a reliable vehicle...

So... Monday, we make a flexplate. This should be fun! Never did this before!

 

[Cumminsfever]

Well... This is taking longer than anticipated... MAKING a flywheel... it started life as a square...

Looks fun but where are our pics of the rig running? lol

I'm curious how this flywheel pans out!

Good things take time... If this is true, this is a REALLY GOOD thing! Lol!

Learning as we go here. Patience is key!

 

[Cumminsfever]

This is what the square plate turned out to be...

Then, we had to make the center hub. It started life as a 4 1/2 inch round chunk of 4140 steel...

 

[Cumminsfever]

This is the finished flywheel... Converter side...

And this is the back side...

And this is the converter side with the centering piece laid in place...
