What are they? Mechanically and cosmetically. Thanks

 

I dont think there are any?

 

I know the motor in the late 06's and 07's are the commonized motors to get the assembly lines ready for the 6.4L's. Not sure what all was different with the commonized 6.0L's but i know the head bolts are slighty stronger. Cosmeticly, the chrome package was added in 06 along with the tow boss package for DRW 350's. In 07, the Lariat Outlaw package was added. Maybe some other guys could chime in if i have forgotten something

 

From 04 to 05 is where you can see the changes... First the Grill from an 04 to 05 is significantly different, or more like bolder. The instrument panel is different, the suspension is beefier on an 05' and newer, the 03 and 04's had 16" wheels and the 05's and newer had 17" wheels standard. Im sure there are alot more things, but those are the ones I can remember off hand.

The '05+ Super Duties moved to larger disc brakes in all four corners. Ford also converted the front suspension from leaf springs to coils. These changes also changed the offset & minimum diameter (17") of the rims.

There were a slew of motor changes/tweaks made, but I have never found a full, comprehensive listing.

 

I'm pretty sure that the Diesel Techs that frequent here have answered this a few times. I can not find the links however.

I do seem to remember that they were all saying the head bolts were not changed. The head gasket did receive an upgrade. There was an article at the Ford Doctors Diesel Technician Society web site that listed the changes. The link is no longer active.

 

Here's the commonization info:

Subject: 2006 6.0L Diesel Power Stroke Cylinder Head Commonization
Effective Date: Ford Production Assembly Plants - January 11, 2006
Kentucky Truck Plant (Super Duty) & Lorraine Assembly Plant (Econoline)
Description
Changes are being made to the 6.0L diesel cylinder head, head gasket, crankcase block, rocker
arm carrier and injector hold down clamps for the 2006 Super Duty and Econoline Program. The
action is taking place to facilitate/communize the International manufacturing process for the
upcoming 6.4L program. The 2006 6.0L used in Ford vehicles after January 11, 2006 are being
referred to as "Commonization Engines".
Part number details are provided on a separate excel spreadsheet.
Figure 1 - New cylinder head
1. Carrier boss bolt holes M10 x 1.5
2. Injector clamp bolt holes (relocated)
The new cylinder heads have several casting changes including a slight injector clamp bolt hole
relocation (2, figure 1) and the carrier boss bolt hole size and location changes (1, figure 1). New
cylinder heads also use 32 mm cup plugs replacing the old 28 mm cup plugs.
The cylinder head gasket is also new to accommodate the new 20mm cylinder head location
dowels. Pre commonization head use 18mm dowels
Note: At this time the new cylinder head assembly is not interchangeable with the previously level
head.
Figure 2 – Previous Level Cylinder Head
1. Carrier boss bolt holes M8 x 1.5
2. Injector clamp bolt holes (original locations)
Note: The previous level cylinder head assembly is not interchangeable with the new head.
Figure 3 - New Block Assembly
The new crankcase (block) uses two 20mm cylinder head locating dowels per head.
The old crankcase (block) uses two 18mm cylinder head locating dowels per head.
Note: The new and old block assembly is not interchangeable. This affects replacement of all 6009
short blocks and the 6010 bare blocks.
Rocker Arm Carrier:
Figure 4 - New Rocker Arm Carrier
Casting changes to the rocker carrier provide increased clearance for new injector hold down
clamps (figure 6). The new carrier also uses only 2 bolts and locating dowels to attach the carrier
to the head.
The new rocker carrier is serviced in a Rocker Arm Carrier Kit which includes the rocker carrier
cover, gasket and necessary dowels.
Note: The new and old rocker arm carrier kits are not interchangeable.
Figure 5 – Previous Level Rocker Arm Carrier Kit
The old rocker arm carrier uses 4 attaching bolts to hold the carrier to the old cylinder head (figure 2).
The previous rocker arm carrier is also serviced in a kit which includes the rocker carrier cover,
gasket and necessary dowels.
Note: The previous level rocker arm kit is not interchangeable with the new kit and will remain
available for service.
Injector Hold Down Clamp:
Figure 6 - New Injector Hold Down Clamp Assembly
The tail end of the new injector hold down clamp is being reduced to avoid interference with the
rocker arm carrier wall. Injector hold down clamp bolt torque will increase from 24 lbf·ft to 25.8 lbf·ft
and bolt head size will increase from T40 to T45.
Note: The new and old injector hold down clamps are not in interchangeable.
Figure 7 – Previous Level Injector Hold Down Clamp Assembly
Note: The new and old injector hold down clamps are not in interchangeable. The old injector hold
down clamp will remain available for service.
