It's a GM engine that's been used in lots of different vehicles, from trucks to Corvettes.

Probably one of the best V8's ever. Simultaneously powerful and reliable, while also being relatively efficient.
I wondered if that was what you were referring to.
I think I have head of guys putting that in the older Land Rovers including the Defender.
I still think GM is correct with their pickups not to follow Ford with the blower type engines.
Land Rover used a small block Buick aluminum engine at one time, but of course made a few changes that screwed it up. I suppose this time, GM could insist LR not "improve" whatever they sold LR.
LR must be the only vehicle manufacturer in the world where the durability of the engine is still hit and miss. I have the 4.4L AJ6 V8 in my LR3 - designed in 1992 I think so by 2005 they had it pretty good - been good to me anyway. Why LR cannot leave well enough alone.....
Per the Wikipedia article, the LS dates back to designs of the fifties with a real update in 1995.
Somehow new variations still meet pollution rules, or skirt them, so that should not be a problem.
LR could save themselves with GM engines; as to the Ford body designs, well we will have to see what Tata does to the Ranger for the Defender.
