The M56 is a really slept on sedan. That engine is decent in the big SUVs so in the M chassis it’s pretty stout even stock, but if you do a proper tune on good fuel they really make some power. 400+ at the tires is easily attainable.
Right that v8 is a monster it moves a big a$$ truck i kno because my😮 dad had a Nissan Armada and that bit move so i kno the m56 move amd its TUNED stop it 😂
