I have 2000 qc with a 4.7 that is getting tired with almost 200k i'm thinking about just swapping it for a another 4.7 how can you tell if you have a 16 0r 32 tone spline before you get into the swap and yes i have searched the forums already. also will a 4.7 from a jeep grand cherokee work if i was able to find one. And thanks ahead for the help.

 

hello, I'm winston, the resident expert on this matter since i just went through a motor swap in my truck. i swapped my 01 dak motor for an 03 jeep ho motor.

the rule is that if it is a jtec pcm (3plugs) it will have a 16t ring. if it has a ngt (4plug) it will be 32.

oh and do not buy your engine from midwest transmission distributors from arizona.

 

is the pcm located passenger side by the air filter?

 

yeah you cant miss it. buch of wires going to it.
