Diesel engine swap

np205 and 6l90e or a 6l80e is pretty easy adapter isnt expensive. you do need to add vss signal pretty easy to do. the 4l80e will also requires a spacer and the vss mod. personally owning both id rather have the 6l90 over all of them. i loved the power and gearing of my 07 truck that had them. if the thing hadnt been thirsty and super prone to rust id still own it. 6.0 vvt with 6l90e is a super strong set up and really powerful. in a lighter truck than my 07 cc lb 4x4 it prob would get pretty good mpg. 6500k weight or more is alot to move around. it got 12 mpg still. now the 5.3 thats in front of a 6l80e is another story. the afm is the issue with them. delete that and its a excellent engine also. keep it you are asking for lifter issues. you want to keep the vvt its solid and really makes the truck wake up. as for diesel only engine id have is a cummins if i was going to do a swap. but in a half ton burban thats overkill imo. you arent going to be pulling 16k behind it.
