Had a brain storm the other day and am investigation putting a Rolls Royce Silver Spirit engine in my P38. I am just imagining the smooth power from the Rollers 6.75 litre V8. So am starting to get some dimensions. The Roller is a 90 degree V8 against the Range Rover 60 degree so will be wider low down but it might work. Plenty of scrap Rollers. The ignition system is Motronic as is my Range Rovers ? Any suggestions welcomed (be polite!)
