The current Rover development of the old GM engine has grown to 4.5 liters, I think. I was still living in the UK when Rover bought the design from GM and a neighbor was the head of Rover's R&D organisation.
They has a standard dynamometer endurance test for an engine design, full power at the design peak rpm for 48 hours without ill effects. Six motors came from GM, the best one lasted 45 minutes! They all broke the crankshaft.
Rover redesigned the block to be sand-cast instead of die-cast, and substantially stiffened the main bearing structure. Their second redesign survived the 48-hour test.
When I was testing for Norton Motorcycles at the Industry Association test track, Rover were doing tests on the first 3500 sedan (with the same body as their "2000" sedan). They were doing full-throttle standing starts at 3/4 mile intervals 24 hours a day for a week. I was surprised that Borg-Warner automatic transmission could take it!
