4.6 Callaway engine in 4.6 HSE

I just picked up a 98 HSE with a bad motor on Thursday. I just picked up a 4.6 from a '99 Callaway today. I know the top end is different, but what do I need to run it? I snagged the engine ECU and MAF, but the air intake tube and airbox were broken in half and missing. I also grabbed the transmission and transfer case. Other than a broken battery cover, and a single lug nut pressed into the mud, thats all that was left. I know the TCU is specific to this transmission, but unless it is located on the tranny itself, I do not have it.

I guess my question is, can I use the stock air intake tube and air box from the 98 4.6? Is it worth taking out the working (apparently) transmission and t-case for the Callaway stuff?

Thanks in advance.

I kind of skimmed through, but are you going to keep it Callaway? IF SO, read:

"The Callaway drivetrain was also modified. The automatic transmission used in the Callaway 4.6 HSE Range has a different torque converter and the transmission control unit (TCU) has been recalibrated to take advantage of the increased torque and power of the engine. The shift points in both "NORMAL" and "SPORT" modes have been changed to match the engine's increased power.

The electronic shift transfer case has a new ratio sprocket set and chain. The resulting new ratios provide a high range ratio of 1.294:1, and a low range ratio of 3.481:1. The ratio change improves acceleration performance in high range while also providing improved off-road "crawl" performance and coast down rates in low range.

The front axle shafts used on the Callaway 4.6 HSE have been strengthened to withstand the increased torque to the front wheels from the engine and transmission changes. A material change in the axles ensures durability will be maintained for the front axle half shafts. <>

Callaway decided to use a four-pin front differential to accommodate the increased torque rather than the two-pin front diff used on standard production Range Rovers. After working with Callaway on the four pin front diff Land Rover decided to put them in all of the 1999 Range Rovers since the 4 wheel traction control that added ABS regulated traction control to the front axle in 1999 also put extra stress on the front diff (Range Rovers from 1993-1998 only had traction control on the rear axle)"
