Rover v8 engine in an Omega? LOL. Only if I wanted it to break down very freqently!!!
The 'Rover' V8 was actually a Buick engine discontinued in 1955, at which point it was bought by Rover and has basically not changed much since.
GM stopped using it in 1963 after producing 750,000 units!!
The V8 engine used by , Rover, Land Rover, TVR, Morgan, Westfield, Marcos, MG etc etc is a damn good engine!
All alloy block makes it very very light and in the hands of TVR produce close on 300bhp from a 4 ltr block, bearing in mind the origional P6 (TC2000) only produce 140ish bhp, that an amazing acheivement.
I would def drop one in an Omega if i had the time and inclination, just need to decide what size ( 3.5, 3.9. 4.6 or 5ltr) as in sure itll be lot lighter than a GM sourced LS1 or LS2 engine!
Also helps that im quite good friends with someone who owns one of the only companies in the UK that can completely overhaul and repair the V8, so ive seen what one can do with a few minor tweaks
