I except Gingerfold’s explanation of the GM V8 in the military Crusader although I tend to think this may well have been the spec for BAOR as I still have written accounts of the MoD specifying the Rolls Royce engine, in fact three versions of the Eagle range were used overall for Crusader models, the 220, 280 and 305. Many Crusaders were used as REME Wreckers and Royal Engineer Plant Transport in particular. One source accounts that although the ■■■■■■■ and AEC V8’s were specified he never came across any that had the ■■■■■■■ fitted. It may be worth mentioning that BAOR vehicles were almost all left hand drive, as you would expect, so when the MoD ordered vehicles they would specify what engines went into particular chassis depending on what theatre they would serve. Franky.
