It's not the 412MI, but what else is?  Note red crackle-finish on the cam-covers, the origin of the name "Testa Rossa", which to the uninitiated, means "red head" in Italian.   

2953cc., 300 HP, 6 dual throat weber carburetors, 2 cams, 12 sparkplugs, and a famous sound, much of which comes from cam-chain resonance.   (Another fun video!)

An extremely successful endurance racer, and not bad in sprints, a Testa Rossa in good hands remains a contender in its class.
