COMP Cams Mutha' Thumpr P8 hydraulic camshaft (287T H-107) is a high-energy flat tappet profile for Pontiac 265–455 engines, offering an aggressive street/strip character with a rough idle. It requires about 9:1 compression and 2500+ stall speed, and benefits from intake, gears and headers to reach its intended powerband and responsiveness.
