1983 110 county v8

Thanks, Im going to buy the 4.6 with top hat liners and the gearbox separately, but I thought that the zf4hp22 also easy fitted to the 4.6, and it’s not as much electronics as the 24. The electronics are the big differences between the 2 right?

Hey guys, Im new with Land Rover defenders, so I need to learn stuff from people with experience so I though this is the place to be. I have a RHD 110 county 3.5 v8 1983. I'm planning to put a p38 4.6 engine in, so I have more power and its economically better on cruising speed. I think the standard engine mount in a 1983 county v8 is already good to fit a p38 4.6 engine, so engine wise that's not bad. I need to make the steering from RHD to LHD because for a daily driver in Amsterdam I think its not a bad idea. My main question is what gearbox should I use? I think the ZF4HP22 is the easiest option, because it belongs to the engine. But I going to make a lot of kilometers on the highway so a r380 with a gear extra sounds good in my opinion, but as I sad im a beginner so I have no idea. Maybe someone can tell what is the best set up for the 4.6 in a defender. Thanks, Mees IMG_7210.HEIC
