Hi guys
I'm new here so I'm sorry for any stupid Q but give me the answer for my questions please

I own a V8 Land Cruiser and looking for more power.
To be clear I need anything possible but no turbo or supercharge, like stroker kit, cam shafts and ported head anything can add hp to my car.
The car now is bone stock
Speed limit 180 Km/H
Manual Transmission
