Hi Neil
Thanks for the information.
I see that there are a couple of 4.oL cars currently advertised.
I know someone who has a 4.6L with a Tornado chip which I know makes the car more driveable. I would have to take advice from more knowledgable owners on heating issues although I have seen it mentioned before.
4.6l are notorious for overheating, and you can spend a lot to get it sorted. I had a 4l 1996 with Chip from Mark Adams with sports exhausts on rolling road it produced 225bhp at 1800rpm and stayed there until 5000rpm when it dropped slightly and masses of torque
