Description

Milodon timing-gear drive assemblies are designed for all-out competition, but work equally well in any application. Their proven fixed idler gear system is capable of maintaining consistent cam timing without siphoning off power the way 4-gear types can. Timing changes are easy via Milodon's adjustable bolt pattern cam gears and hub assemblies. Made for strength and durability, these gear drives will last indefinitely. They are available in a flat-cover style, which uses a stock-type water pump, or an injected/blown style, which doesn't use a stock-type pump.
