I don’t know a ton about foreign motors other than surface level stuff like the 2JZ, Wankel, etc. so please forgive my ignorance outside of US motors.
However, in my eyes, it doesn’t get better than the simplicity and easily available power of the SBC, BBC, and 6BT. What are your all time favorites and why?
The Ferrari F140 V12, Pure naturally aspirated V12 magic.
The highest 6.5L street version making 829HP, 530ft/lb, and redline at 9250PRM.
This engine is everything engines should be.
The V8 that topped out in the 458, also just pure magic. In so many beautiful sounding cars.
