COMP Cams Big Mutha' Thumpr P8 hydraulic camshaft (295T H-107) is a big flat-tappet street/strip profile for Pontiac 265–455 engines that produces a very rough idle and favors high-stall setups. It calls for roughly 9.5:1 compression and 2800+ stall speed, and performs best with appropriate intake, gearing and headers to harvest its powerband.
