900-1400whp

GSC5078 Conical

• A common concern when picking out a spring kit is adding too much spring pressure, especially in street applications.  When it comes to the spring, more pressure is better than less pressure.  Less pressure will result in valve float which can cause damage to your valve-train.

• The correct amount of pressure will keep the springs controlled which in turn controls the valves.  The number one cause of valve-train and or cam/bucket failure is not having the correct valve spring for your application.  If the valve spring is not happy, nothing will be happy.

900-1400whp

Option 1: 242 degrees of duration @1mm

Option 2: 25X@1mm

•  Are you planning to set world records or make big power?!

• If you’re range is 1400-1600whp a cam with approximately 240 degrees of duration @1mm (.040) is what you’ll want.

• 1600whp+ we suggest going to 25X@1mm (.040) degrees of duration.  You will need the duration to run the big RPM numbers!     

• Doing this will lead to lots of area under the curve that will keep you in the winners circle.
