COMP Cams Thumpr 299 grind for street and strip applications, delivering aggressive idle and substantial power gains. This cam typically requires about 9.5:1 compression, a 2800+ stall converter, upgraded intake, gears and headers, and produces a very rough idle. It suits builds that pair valvetrain and driveline upgrades to support the more aggressive timing and overlap.
