Modified cam timing, carburetor changes and enlarged intakes boosted the engine output to 385 HP @ 7850 rpm. More rigidity was designed into the front and rear portions of the chassis; similar changes are often incorporated when older Miuras are restored.
Some (but not all, as is often thought) of the SVs received the quite valuable "split sump" treatment, seperating the lube system between the transmission and the engine. A few SVs were equipped with a limited slip differential.
Lamborghini ended production of the Miura SV when it built s/n 4822 on October 12, 1973. Just over 750 Miuras were built.
Most car models end their production run when demand ceases, but this was not the case with the Miura. By all accounts they could have kept selling it as buyers were still eager. But Lamborghini had a worthy successor waiting in the Countach and their limited manufacturing facilities could not accomodate two models. The Countach continued the Miura tradition and also became an exotic car benchmark, setting new standards in styling and technology. It further revolutionized drivetrain systems with a mid engine layout (this time in line) with the tranmission in front of the engine. The Countach succeeded wildly, becoming a high end icon in the eighties. But it all started with a small group of ambitious young engineers with a dream called the Miura.
