It sure would - especially if you want to use unleaded fuel and not worry about valve seat regression (assuming you get an alloy head x-flow).
I have just installed a crossflow from an XF into my ZC Fairlane and it all works really well...
I used all the XF wiring loom and quite a bit of the other XF stuff (including the exhaust system)
For an investment of $300 (including the tow truck) I got a 1986 XF Wagon and swapped over engine, gearbox, steering column, wiring loom, cool air intake, battery tray, diff, A/C condensor and engine bay hoses.
I ended up using a radiator from an XA V8 with the appropriate mounts (slight mods required for the bottom mounts), but I am pretty sure that the XF radiator would fit (my XY Wagon has a wide XF radiator installed)
I reckon the XF radiator is probably a better choice (free if you get a good one in the donor car), but by the time I had worked that out, I had already forked out $400+ for a brand new XA rad, which has giant tanks anyhow so it is probably 6 of one half a dozen of the other.
Both rads really needed some of the radiator support panel cut away to make them fit properly with the factory brackets.
With the XF conversion, you get a few features that are nice to have:
- Runs on Unleaded fuel with no additives required
- Modern, thick rimmed steering wheel of legal (factory) size
- Hazard light flasher
- Headlight flasher on the column
- Wiper switch on the column
- Electronic ignition (no points to wear out)
- Factory Aircon equipment (indoor unit still required)
- Honda designed, true "Hemi" head
- Easy path to EFI induction
- Lighter engine than iron head 6
To get the electronic ignition loom into the cabin without the giant oval hole that they used on the XF, I took the clutch blanking plate off and fed all the engine bay connectors through from the cabin side (I had to cut the distributor and testing plugs off and join them back on with connectors because they were too big to poke through the hole)
I can probably answer most questions you may have about all this, so ask away.
Cost-wise, this is by far the best engine conversion I have done to the Fairlane... (5th engine since I have owned the car)
