Comp Cams 34-432-9, XR282HR-10 Big Block Ford 460 Camshaft – Hydraulic Roller Retro Fit

The Comp Cams 34-432-9 XR282HR-10 is a hydraulic roller camshaft built for strong street and strip performance. It delivers a broad power curve with crisp throttle response, strong mid-range torque, and impressive top-end pull. Designed for engines with higher compression, performance cylinder heads, and upgraded valve springs, this camshaft balances drivability with serious horsepower gains. Ideal for enthusiasts seeking a noticeable idle and reliable performance on pump fuel without sacrificing everyday usability.

Characteristics:

• Delivers strong mid-to-upper RPM power while maintaining reasonable idle quality and usable vacuum for street driveability.

• Provides excellent mid-range punch without sacrificing too much bottom-end torque.

• Lumpy idle and a great all-round camshaft for fun, cruising, and hot rods.

• Perfect for hot street F100 trucks and similar builds.

Modifications / Applications:

• Suits 429+ and 460 engines with a stall converter of ~2200+ RPM.

• Recommended for engines with compression above ~9.0:1 and supporting mods like headers and performance intake.

• Works best with aluminium performance intakes and ~10.2:1 compression.

• Valve springs must be upgraded – we recommend DRP-9415P-16 Dual Small LS Diameter springs.
