The engine mounts tore due to increased engine output.
Radiator coolant contaminated the engine oil from alloy-head trouble.
Brakes needed attention.
The TE with the 250 Cross-Flow is a great combination and even when stock will pull 17second 1/4 Mile with auto and 185R13's.
My TE has been retro fitted with Electronic Ignition from an 1985 XF Falcon. This eliminates points.
It has the EFI Alloy head which flows more than carby head and has been shaved 35thou for 9.42:1 Compression.
I run the Weber carby re-jetted and attached to the redline 2 barrel manifold that suits a 350 holley.
With a Pod filter and bonnet scoop the temperature stays down and more air gets into the engine to help it rev.
I have also fitted a T5 5 speed manual with lightened flywheel which is much faster to 100 than the auto ever was.
With the above combo and extractors, 2.5" mandrel bent exhaust with one lukey resonator this cars is damn quick and can beat XR6 Falcons.
I can now do 0-100km in 6.5 seconds.
I have a TE Cortina 2lt that I have just finished rebuilding. I found the same over heating problems that I read so much about. If you don't want to cut into the well designed bonnet, simply remove the thermostat and reattach houseing. Yes it will take longer for the heater to blow hot air, but you won't ever over heat your engine or crack your alloy head on long or fast trips. I towed a 1800kg caravan to Sydney from Adelaide and back and she handled like a dream after I replaced the back suspension with air assisted shocks and PROFESIONALLY loward front struts.Don't ever use alloy heads as you will find that within a year of tromping it, it will die. Take the experience of an old mechanic. Cast iron even rebuilt is better!!!
