I posted this in the Gen 3 Hemi forum,but thought I'd try here also.I have a 2004 Durango Hemi,I started sourcing parts to rebuild the blown-up original motor.New block,etc...The abudance of low mile later('09 + up) engines has me wondering if they can be swapped into the earlier application.I realize they have VVT and some MDS,guessing the tone ring count may be different also,I'm just looking at options and wondering if anyone has attempted this with any success. Thanks,RT
