Star 3/4 Race Milwaukee-Eight Camshaft — .585 Lift

Maximum reliable performance paired with a dual-lobe profile built to wake up big-bore Milwaukee-8 engines from 2,500 RPM to redline.

 

Part Description

The Star 3/4 Race Milwaukee-8 Cam delivers the most lift available for reliable, street-driven performance and pairs exceptionally well with 128–143 cubic inch big-bore kits. With .585” lift and an intake closing point of 42° ABDC, the 3/4 Race features a unique dual-lobe profile that combines low-to-mid range torque on the intake side with top-end power on the exhaust side. The result is a cam that pulls hard from 2,500 RPM and keeps building all the way to 6,500 — exactly what a built engine deserves. 

 

High performance valve springs and lifter guide upgrades are required. Star M8 Valve Spring Kit (640SK-2) and Star Gold Lifter Guides (M8726LG) are recommended.

 

**Please note that we cannot ship cams to California. California customers please contact Moto Performance Garage of Las Vegas.**
