Default Blew up the HEMI today

its been a long time since i have had to be on this thread for help, but do to certain circumstances i need everyones help again with my motor problem.
Last Friday as i was driving into town from work my truck started to vibrate like a kid at the candy store. I pulled over shut the truck down then tried to restart it and nuthin just a thud. well i towed it to my buddys to find out the engine is pooped, broke the #1 piston rod, screwed the crank and block into mush and pretty much just destroyed my engine.
The problem i am having is trying to find a new motor, I have been looking all over Manitoba and Saskatchewan this week for a used Hemi without MDS since my truck is a 2004 Dodge Ram 1500 but to no avail.
What i am wondering is can i throw in a 5.7 hemi with MDS into my truck, and what other procedures i would have to switch around.
If anyone has done this before or if anyone close to Manitoba has a used hemi for sale let me know please. Its driving me crazy not having my truck on the road so any help is greatly appreciated.
Thank you,
Myles

Yeah I would look on ebay and craigslist but why cant you just swap out the lifters and yokes from the MDS ones to the non-MDS lifters and yokes?

I dont see why not but you would need to look at one and make sure all the sensors are the same and in the same place. Thats what I would do

If you do go with the mds. I think a wiring harness would be in your future. It can be done, You gotta think outside of the box. Lotta work too.

No the 03 wont work in the 04 for the same reason the 04 wont work in the 03. Separate PCM and TCM in the 03 make the swap not possible. The only direct swap motor besides an 04 he could do is an 05.

That makes no sense compared to weeds post. Pretty sure the motor does not care that the PCM is different. Unless they changed any of the sensor styles or locations (doubt it) then it should work. Even with the MDS motor just un MDS it with the lifters from the 03 to 05 Hemi. I was eyeing up a 2006 Hemi from an HD (no MDS) and all the sensors that I could visibly locate looked all the same.

You can even use a MDS engine, just the MDS will not function. You can use your older coil/plug wire set up along with your valvecovers unless you want to rewire all of the coils like weed did on his. If you do get a MDS engine, just be sure to use 5w20 oil only.

If you get an 03 engine, remember that 03's don't have EGR.

Hold tight buddy.
What happened to you is a COMMON PROBLEM with 2004 5.7 hemis.
This happened to me last week, rod when through the block for NO GOOD REASON. I keep 100% maintenance on my '04 Durango. I told myself this is just a fluke, bad luck. Know guys that race their Hemi Dodges and put NOS to it with no problem.
BUT looks like this problem is particular to 2004 5.7 Hemis.
There is enough people with expensive trucks and Durango that are rendered junk that there should be a class action law suit.
Go to the NHTSA web site and register a complaint.
Check this out if you don't believe me.

Read the posts in that thread. You will be highly pissed because your truck took a dump for a likely KNOWN PROBLEM that are not going to fix.

you can use a 2003-2005 Motor as a direct replacement.The mds on the 2005 won't work with your wiring harness,and there is only one difference between a 2003 and 2004 motor,other than the TCM..that is the oxygen tube that runs from the front head to the intake manifold on the left looking at the motor from the front..If you find an 03 take the one off your old motor.You're right about the 8th digit Any 8 will work..
