hey guys i have an 4x4 1989 dodge dakota standard cab long bed LE package and it currently has the 3.9L v6 in it i have a few uestions about swapping a 5.2 into the truck.
1) will the V8 bolt right in?
2)since this truck is already fuel injected can i use the same throttle body off the V6? yes i know it will suck some power
3) will the automatic tranny, tansfer case, and diffs hold up to the power of the 318?

 

:P
These questions have been asked a million times in this forum.
Do a forum search, check the FAQ area (lots of great info there)

Answers in a nutshell:
1) Yes and no. Define "bolts in". Due to increased length, the fan needs to be replaced with electric one. Some other small changes.
2) You use the fuel system, computer, harness, etc. from the 5.2.
3) The V8 has a stronger trans, not sure about Transfer case.

Read up in the forums. I've not done the swap but many here have.
