Is it possible to swap a dodge ram 1500 2007 5.7l Hemi engine into a 2005 Dodge ram 1500 5.7l truck?

Mechanic's Assistant: How many miles are on the car? Is it an automatic or a manual transmission?

Its an automatic and the old engine in the 2005 isn't good.

Mechanic's Assistant: Are you fixing your Ram 1500 yourself? What have you tried so far?

I have a garage on standby and would like to know if its possible to swap a 2007 5.7l hemi in2005 ram

Well the 2007 have mds and the 2005 doesn't, I would like to know if I need to change the computer and or any other parts

1N4AL21E08N533908 for the 2005 ram 1500 5.7l

i have the vin home at this moment I'm at work

The two can be swapped as far as fitment, you would have to swap the valve covers, But let me make sure on the rest of the electrical system. Be right back.

Ok yays that's awesome news. okay! :)
Customer reply replied 4 months ago
the only thing one worried about is the MDS in the 2007. as my 2005 carries no MDS

From all I see this swap is a go. As I said you will have to swap out the valve covers so the msd coils will bolt up, but I do not see any reason there would be any other parts need to be swapped out other then the intake.

Ahh i see so no ECU changes and the engine will work and run without MDS as they are not commands to activate it
Customer reply replied 4 months ago
I will take your final advice and order this engine for my truck. I really appreciate it. all the other 2005 models are higher milage and i found on that's 82k 2007 which is pretty sweet as its a long block. thank you and have a wonderful night!

You have to use the ignition system for the truck the engine is going into. As long as you use all the parts from the old engine to the new one, you do not have to do any wire changing or ecu swapping. All you can use will be the long block itself, all the rest must come off of the old engine.

Ask Your Own Dodge Question

I am sorry I may have confused you. I was thinking the 05 was going into the 07, but you are going the other way, so no you can not use the msd set up, you have top swap the valve covers and use the ignition system that is in the truck now, not the one that comes on the engine.

Okay ill swap the 2005 valve covers on to the 2007
Customer reply replied 4 months ago
No ECU changes or wiring changes.
Customer reply replied 4 months ago
the 2007 Hemi will be swapped into the 2005 Ram 1500.

Then just put all the accessories on the 07 off of the 05 and you should be good to go.

Customer reply replied 4 months ago
Ahh thank you. i will do just that.

You will also have to swap out the timing cover and may have to swap the oil pan as well.

Ask Your Own Dodge Question
Customer reply replied 4 months ago
Ok, ill have all of this info presented to the mechanic, once there is no issues with changing the ECU then we're good to go.
Customer reply replied 4 months ago
do i need to remove the MDS lifters?

No. you can run it just the way it is.
