Look for pushrods and valvesprings elsewhere in the Under the Hood category. See above for installation tip and dyno results.
NOTE: We do not accept returns or exchanges on camshafts. If there is a defect or problem, we will of course take care of it, but we cannot accept returns on these. Please order carefully.
Instead of pulling the engine, simply drop the passenger side of the engine cradle about 5 for easy access to the camshaft. Click picture for larger image.
The car was our 2002 Grand Prix GTP with only 740 miles on the odometer at the time. The only horsepower modifications at the time are exhaust components. The car still has the factory supercharger pulley and factory airbox including paper filter. The only thing we changed was the cam; all other valvetrain components remained stock. We saw a gain of 22.5 hp and 24.5 lb-ft. of torque at the wheels which equates to about 28 hp and 30 lb-ft. of torque at the crank, a substantial increase of over 10%. As one might expect with a gain of this magnitude, there is a VERY noticeable difference in the performance of the car.
