@Lord Buckethead was taking the mickey.
Yep sure was, they did the original 3L version. Rover bought the tooling when it was being phased out.
Apart from their Rover P6 and SD1 saloons it became the go-to kit car engine. The V8 being nearly as light as the 4cyl cast iron job it was replacing.
Models include, Morgan, MGB, Triumh TR(7) 8, Triumph Stag.
Both Triumph and Rover were at one time under British Leyland but like rival 13yr old girls olds 'didnt talk to each other' Rover had the excellent V 8 ready to go for the Stag. But Triumph made their own by cobbling together 2 of there crap 1500 4 cyls. into 1 super crap 3L V8...more British Leyland waste for you.
I've also seen the Rover V8 in Mk I & Mk III Cortinas and various japanese frames.
