How difficult would a New Hemi Conversion be for a
67 Fury III? Im doing my homework on this before I even take it as a serious possibility.  

You've got plenty of room for the engine, you might have some clearnce trouble though with the master cylinder and steering box. The guys at Mopar Muscle are working on putting a 6.1L HEMI in a coke bottle Charger right now.  

Alright, any tips, personal experiences. Im currently in Korea, but Im hoping to start the project right aroung Thanksgiving. Pulling the engine from a wrecked magnum.
How much of a hassle is it trying to get all the electronic interfaces meshed with a car that hasnt even seen a sterio, much less a engine diagnostic tool?  

Street and Performance in Arkansas sells the stuff old-guy street rodders need to adapt the 3G Hemi into their rods, so some of what they sell probably could be used to put a 3G Hemi into a later model "steet machine."

If you don't want any computers (and are willing to give up on the free torque and economy from EFI ram-tuning) Arrington Racing Engines in North Carolina also is introducing a kit that will convert the 3G Hemi into a carbureted mill with a conventional distributor and no computer (requires an Arrington timing cover).  

with gas prices rising to rates that threaten this hobby, I better go with the EFI tuning. i was looking at the XV Motorsports setup, currently looking for any others.
Keep this thread going I can use all ideas feasable.  

TTI (Tube Technologies Inc) sells engine mounts to put the 3g hemi into A & B bodies.  The mounts are the same in a C body like your Fury.  They do not carry headers for the C body.  You would have to use the factory exhaust manifolds or have custom headers made for the application.  The electronics can be pulled from the donor vehicle or acquired from Street and Performance.  I heard a rumor that F.A.S.T. (Fuel Air Spark Technologies) was working on a stand alone computer for the 3G Hemi, but I haven't talked to them yet.  Good luck, sounds like a reat project!
