Valve Springs

The camshaft specifications you provided (Part No. 3231393T & 3241393) indicate a mild camshaft suitable for mid-range performance with a choppy idle. Here are the key specifications for this camshaft:

• RPM Range: 2700 – 6200
• Part Numbers:
  • Intake Camshaft: 3231393T
  • Exhaust Camshaft: 3241393
• Advance Duration (Degrees):
  • Intake: 259
  • Exhaust: 259
• Duration @ 0.050” (Degrees):
  • Intake: 195
  • Exhaust: 195
• Valve Lift (Inches):
  • Intake: 0.452″
  • Exhaust: 0.452″

These specifications suggest a mild camshaft that provides good mid-range torque and a choppy idle, enhancing the engine’s overall performance. Here are some considerations for the installation of this camshaft:

1. Valve Springs: The specifications indicate that standard valve springs can be used. However, it’s essential to verify that the stock springs are in good condition and match the camshaft’s lift and duration.
2. Engine Tuning: While the camshaft is mild, some adjustments to the engine’s tune may be beneficial to fully optimize performance. This includes adjustments to the air-fuel mixture and ignition timing.
3. Computer Calibration: Ensure that the engine management system is calibrated to accommodate the new camshaft specifications. Some modifications to the computer may be necessary for optimal performance.
4. Choppy Idle: The choppy idle characteristic is a result of the camshaft’s specifications. It adds a performance-oriented sound but may not be suitable for all applications, especially if smooth idling is a priority.
5. Not Suitable for FG: It’s noted that this camshaft is not suitable for FG. Ensure compatibility with your specific vehicle model and engine.

This camshaft should provide a noticeable improvement in mid-range torque and performance while maintaining a relatively mild profile. If you have any further questions or need additional assistance, feel free to ask.
