I have a 2005 5.7 hemi ram 1500. Engine shot. Yard sold me a 2005 durango motor and said would bolt in with ex manifold and oil pan change. Original tranny will not fit . What motor will fit tranny and work without changing electronics. In other words, a real bolt-in.
thanks.

 

If they sold you a hemi out of the Durango, then it should bolt to your trans, it is the same engine. Using your sensors from your old engine should be plug-n-play. Are you sure they sold you a hemi? Even a 4.7 uses the same trans.

 

I'm not sure how to know if its a hemi. People installing it say the torque converter will not fit the crankshaft. they miked it and its bigger. If its not a 2005, does that matter? Will the vin tell me anything?
thanks

 

The vin will tell you yes. Is the donor engine complete? Is the alternator on the left (drivers side) or right (passengers side) of the engine? The 4.7 will have the alternator on the drivers side.

 

5.7 3rd gen hemi:


4.7:


Regardless, trans and TC will bolt to both equally well.

 

This is why I tell people never to buy "good" junkyard engines and to rebuild what they have.
