Lamborghini Miura

Lamborghini Miura Dyno Video

This Muira engine is similar to the Espada. The stock exhaust headers are of a different design and this example had some mild cylinder head porting done, but otherwise is basically stock. The cam timing was set at non-stock values as well. The power is good, but not quite up to the alleged factory figures of 350-385 HP. An interesting side note is that, according to Bob Wallace, the Muira engines were really never tested by the Lamborghini factory due to the lack of a local dyno that would rotate counter-clockwise!
