what does it take to put a 99 factory 4.0 in a 97? the 97 has a factory 4.0 in it that is blown up and im just trying to find out what the range is for a factory swap to put another 4.0 back in it. would a 99 be a direct bolt in or what all would have to be changed to put a 99's 4.0 in a 97?

 

You can use the long block for sure,I am pretty sure you can use the controls also,meaning intake exhaust,flexplate etc. I would look at the coneectors and make sure the are the same,electrical connectors. The 99 has a different head but it should not be an issue.

 

how about the computer plug ins would they be the same. could i use the 99 computer in place of the 97 computer and everything inside work properly? if i take the 99 motor, wiring, and computer and put them in the 97 will the wiring plug straight in and everything work like its suppose to?

 

What are you doing with the blown 97 4.0?? Pm me with a price if you are willing to part
