4.0 Swap

[ajs_customs]

Hey guys I have another question about 4.0's
I have a 90 2wd 4.0/a4ld with a bad engine.
I have access to an explorer built 4/91 4.0/a4ld 4wd.
The question is, will this engine swap with my truck or am I going to have to change all the wiring and ecm. I am looking to do this on the kinda cheap.
Thanks guys.

Should work no problem, they are both 4.0l OHV motors. I'd check the exhaust manifolds, the bad motor may not have had EGR ... can't remember when they first started doing them.

93+ California has EGR
94+ everwhere else

91 also had EGR I believe
92-93 did not

If it is an EGR motor then I should be able to just swap intakes shouldn't I? I haven't picked up the donor truck yet to tell and its a ways away right now.
Thank you guys for the help.
