Rover 3 litres of that era (and the late Humber Snipes) are quite nice cars but suffer the common pommie design fault, overweight and underpowered. Too much pudding and not enough engine. Range Rovers are a classic example. That GM engine family that the 3.5 and later Rover V8's came from were out at 300 c.i. and later at 350 with aluminium heads and iron block. In V6 form they eventually reached 4.3 litres turbocharged so why did Rover build a ****ant 3.5 litre to move a 2 ton car?
Stick in the easily obtained Chrysler, an easy conversion, and get yourself a nice gentleman's carriage with performance. Late Snipes with one are a lovely car. The Chrysler is a good bit lighter than either the Rover or Humber engine and almost 50% greater capacity. Nothing beats cubic inches.
