The last and most famous Miura, the P400SV or Miura SV featured different cam timing and altered carburetors. These gave the engine an additional 15 PS (11 kW; 15 hp), to 385 PS (283 kW; 380 hp). The last 96 SV engines included a limited slip differential which required a split sump. The gearbox now had its lubrication system separate from the engine, which allowed the use of the appropriate types of oil for the gearbox and the engine. This also alleviated concerns that metal shavings from the gearbox could travel into the engine with disastrous and expensive results.
The SV can be distinguished from its predecessors from its lack of “eyelashes” around the headlamps, wider rear fenders to accommodate the new 9-inch-wide (230 mm) rear wheels and Pirelli Cinturato tires, and different taillights. 150 SVs were produced.
There was a misprint in the SV owners manual indicating bigger intake valves in English size (but correct size in metric). The intake and exhaust valves in all 4 liter V12 Lamborghini remained the same throughout all models. This intake size misprint carried forward into Espada 400GT and Countach LP400/LP400S owners manuals as well.
