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're 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.
