Hi all,
I recently bought an FZJ80 from a member here with a severely overheated engine. The rest of the truck is in relatively good shape; minor surface rust on the underside but all the body panels are rust free (which is rare for an MN 80). The plan is to do a 5.3 swap with the Marks adapter but retain the stock ride height. I've read virtually every V8 swap thread on the forum and the consensus seems to be either you need a 3''-4'' lift or smaller diameter front driveshaft. I would prefer to either notch the transmission pan and/or shift the entire engine up and to the drivers side. I know a few MUD members have done this before but I haven't found much documentation.
Some other notable items I have planned for the build:
Old engine seems pretty cooked

Some other notable items I have planned for the build:
- Dirty Dingo universal engine mounts
- Larger radiator (Don't trust the OEM one after it was overheated)
- Custom PS/AC lines
- sourcing a full 5.3 4L60e pullout with harness/ecu/pedal
- maybe a new fuel system?
