real steel cyclone
best power band for a heavy range rover and is a straight swap -if you run a cam with more lift (JE 102, piper 270, real steel stump puller) then you need to remove 0.1inch off the top of the valve guide and use double springs to avoid coil bind, bounce and resonance. These cams will make more power at the top end but you will loose out on low-mid range torque so are not really best suited to a car like the range rover.
