Triumph V8 engine

The Triumph V8 is a 3.0 litre V8 engine developed and built by the Triumph Motor Company for the Triumph Stag. It grew out of the slant-four, whose designer Lewis Dawtrey had foreseen in 1963 that the design could be doubled up into a V8. The first plan was a 2.5 litre engine with Bosch mechanical fuel injection, but the injection proved troublesome and was dropped for twin Zenith-Stromberg carburettors, with capacity raised to 3.0 litres by enlarging the bore. The result is an oversquare engine with a chromium iron block, aluminium cylinder heads and a single overhead camshaft per bank. It launched in 1970 and stayed unique to the Stag, because plans to fit it to the Triumph 2000 saloon and to sell it to Morgan and Saab came to nothing.
