VHM Spec Vented Camshaft

Description

The VHM Billet Vented Camshaft is the first of its kind, designed to help relieve crankcase pressure in Milwaukee-Eight high-performance engines. Its vented design promotes better ring seal, helps minimize oil-pump cavitation and allows the engine to operate more efficiently. It can also be used with our ProVent Engine Breather (P/N 41-1000 and 41-1100) for additional crankcase ventilation.

Developed for 121ci and larger Gen 1 and Gen 2 non-VVT models, this camshaft is ideal for high-compression builds of 11.5:1 and above. Its aggressive profile delivers strong power and torque throughout the mid-to-upper RPM range while maintaining smooth operation.

Features Include:

• Precision-machined billet construction
• Vented design helps reduce crankcase pressure, improve ring seal and minimize oil-pump cavitation
• Designed to work with VHM ProVent Engine Breather
• Silent-ramp profile helps reduce valvetrain noise for smoother, quieter operation
• Requires high-lift valve springs with a minimum lift capacity of 0.560″
• Optimized for use with VHM-spec pistons; valve-to-piston clearance should be verified with other combinations
• Hydraulic roller design minimizes friction and wear at high RPM
• Operating range of 2,000–6,800 RPM
• Proudly made in the USA
