If i remember correctly, if you use your old intake & heads, & all the sensors on just about any 5.7 L HEMI engine from 2002 MID YEAR on up
Including out of Jeeps & cars
The Ram 1500 starting in 2006 & newer had MDS & you don't want that, but you can use the short block out of them
None of the 2500 & 3500 models had the MDS, but you will still need your old intake manifold & all the sensors
There may be other things that i have forgotten, so double checking is in order
The '5.7 L Hemi' was released for model year 2003 on the Dodge Ram 2500 and 3500 pickup trucks to replace the Magnum 5.9 engine. It also replaced the 8.0L V-10 engine in the heavy duty Ram. As of 2004 it was the only available gasoline engine in the Ram Heavy Duty. Chrysler has since made the 5.7 L Hemi available in all models of the 2004 Dodge Ram, Dodge Durango, the 2005 Chrysler 300C, Dodge Magnum R/T, Jeep Grand Cherokee, the 2006 Dodge Charger R/T, and the 2009 Dodge Challenger R/T. For Challenger, the 6 speed version will not feature MDS.
