2012 truck engine in a duster

I am new to this forum but had A bodies all my life.i recently acquired a 2012 ram 5.7 complete with engine harness, no pcm.i would like to put it in my 1970 duster 4spd,Bolting the engine in the car seems easy enough ie mounts , exhaust and mds delete . I would like to use the factory fuel injection and possibly the vvt system . Called mopar performance about using their crate motor installation kit and was told it will not work on this year engine. Has anyone use the mopar kit on engine other than their crate motor
