2002 4.7L to 5.9L Swap
 

I'm looking into putting a 5.9L from a 2002 into a 2002 that has a 4.7L. I've searched the threads and can't really find anyone who's done this. Most are Hemi swaps. I know most of your opinions will be that I should put in a Hemi. That would be nice, but the used 5.9L's are significantly cheaper than the Hemis and 4.7's. So I'm trying to find out if it would be more feasible price wise to use a 5.9L.

So my questions are.....
Will the 5.9L bolt right up to the transmission from the 4.7L?
Will new motor mounts be required?
Is it as easy and just swapping the computers or does the whole wiring harness need to be changed too?
Is there anything else I'm missing in this swap that would prevent it from running correctly or that would be a large cost?

Thanks for any info.

Have not heard of it being done, but it's do-able.

HOWEVER if you are not buying the 5.9 as part of a "donor vehicle", I wouldn't even consider it. If you just buy the engine, you'll find you will go broke buying up everything else you'll need to pull it off.
