Points granted, but the Triumph V8 was a POS - it had all kinds of trouble with cylinder heads warping because of inadequate cooling, its head gasket design was crap and the water pump design was inadequate (both of which added to the overheating problems), the main bearings are much too small and the anvil-tough chromium-iron block didn't match well with the aluminum heads. The design of the engine was simply compromised by so many compromises made in its design, and in my world the Rover V8's existence simply made the Triumph V8 unneccessary unless you could make the two use common components. That's possible, but not easily done outside of engine ancillaries such as fuel and intake systems.
Agree that the OTL Triumph V8 is rubbish and could have done with a lot more development at best, which is why ATL Triumph is better off continuing to work with Saab on Slant-4 (and other ATL related) engines until the ATL V8 further developed to at least form an earlier basis of the OTL Saab V8.
