Milodon 12700 Big Block Chevy IV, Timing Gear Drive, Hex Cam Drive, Billet Gears, Timing cover, Kit

For over 50 years, Milodon Gear Drives have been acknowledged as the ultimate in quality, strength and durability, whether the use be Top Fuel, Circle Track, Drag Race, Marine or Pro Street. There are lots of gear drive units on the market today, most of them are from overseas. None of them can match the American made quality and experience of Milodon.

Even though Milodon Gear Drives are designed for "All Out Competition", they work equally well in ANY application, including Street. When installed properly, these units will virtually last indefinitely due to the zero wear and their overall brute strength. Cam timing accuracy and consistency are the key to accessing 100% of the cam's available power. A timing chain or an "easy to install" $150 gear drive can not provide this.

Milodon's professionally proven "Fixed Idler Gear" system is capable of maintaining the precise cam timing required to allow the cam to work to its maximum potential power. Cam timing adjustments are easy to perform on the Full Cover Style Assembly through the removable billet cam cover. The adjustment is achieved by changing the position of the cam gear on the cam hub. A simple bolt-on procedure with no offset dowels or keys to mess with. Each movement is detailed on a provided chart which gives the exact position for the desired amount of advance or retard, once top dead center is found.

A professional style three gear unit, unlike a four gear type, does not rob any power from the engine. The billet steel gears mounted solidly to the block, that will not and can not allow the timing to vary, unlike a flexible belt or chain. These factors add up to increased horsepower output and higher RPM potential.
