I have a 1999 durango with a hole in the block,,,what kind of issues if any will i run into if i put a 5.9 in its place,,,will the ecm need to be changed or will the 5.2 computer run the 5.9. Will there be any trans issues too?

 

trans SHOULD bolt right up, but it will likely not last for too long with the extra torque of the 5.9 going through it, and the motor mounts should match, im not sure about the pcm

 

I am rebuilding the trans,,,is there anything i could change in the trans now.. Also I have a chance to buy a 360 with a trans attached,that trans will need to be rebuilt,,,any thoughts?

 

definitely put a shift kit in there, if it were me i would replace all the sensors/solenoids in it too and probably drop the check valve out of the line to the trans cooler as it is prone to clogging and eating the trans

 

Also I just found out the 360 I am thinking about getting has EGR,,, the 318 intake and manifolds should be just fine on the 360,,,right?

 

The other 5.9L is a pre-magnum motor?

 

what is the 5.9 coming out of (year) is what i think hydra is asking, the magnum engine run was from what 95+????

 

Magnum engines 1990-2001

 

I beleave it is a 96,, but like i said it has egr,,,,I know it is a magnum,,I seen it

 

is the 96 OBDII???? (im not sure exactly which year the switch was mandatory, but i konw it was around 96)

i think the engine needs to be from an OBDII truck in order to work properly
