Star 3/4 Race Milwaukee-8 Camshaft - .585 Lift
$369.95
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.

Exhaust pairing matters: Star Cams will perform with all pipe configurations, but exhaust selection has a meaningful impact on results. Short exhaust systems create sound wave differentials that negatively affect low-RPM tune quality — a condition that cannot be fully corrected through tuning alone. For the smoothest low-end torque curve, a long 2-into-1 exhaust is strongly recommended. Trusted options include D&D, Fuel Moto, Bassani, ThunderHeader, and Krome Werks.
Professional tuning recommended for best results.
