Just found a engine with transfer case for a very good deal. I'm assuming the 4l that is coming out of the 01 explorer is a SOHC. how big of a headache will the swap be?

 

Yes, should be 4.0l SOHC in 2001 Explorer, and should have the timing chains and tensioners updated before installing, 1997-2003 4.0l SOHC had the bad tensioners

Basically the same as swapping in a V8 or any other engine that's not the original size in the 1996

Engine/trans, computer and wiring harness
Maybe drive shaft changes, length
Exhaust system, maybe just custom bends to match up manifold connection to pipes, if 1996 is a V6
Radiator unless hoses match up


IMO, this is not a "good swap" because you can go out and buy a 2001 to 2011 Ranger with 4.0l SOHC already installed, and a factory install
The V8 swap was popular because its the same parts and work but not available from factory

 

Gotcha......I'll wait for a v8 out of an explorer or mountaineer to come around.

 

After some time searching and pondering a V8 swap.....at the moment I just want to find a 4.0L engine to replace the one in the truck.....You know one that doesn't labor knock and have a ear piercing vacuum leak under a load at 2000 rpm...
