Biggest cam for stock 350: Buying guide

Before getting your biggest cam for stock 350, you need to consider a few things to choose the right one. Since it is an exhausting task to choose among the myriads, so you can look at my purchase guide for guidance.

  • Compatibility: The cam’s compatibility with your engine should be your prime concern. Try to avoid choosing over-duration and excessive valve lifts, as they should be in normal ranges. Or else, there are potential risks that your cam would lock up in position. Read your engine’s specifications before you head over for a cam.
  • Lobe Angle: This angle mainly determines the simultaneous opening and closing of the exhaust and intake valve. For engines that need to increase their street performance, they need expanded lobe separation angles. However, racing cars need narrow lobe angles for high-speed performance.
  • RPM range: The RPM range should match that of your engine’s specified requirements. Too low RPM than required will cause under-performance, hampering hp and torque. And too high RPM can devastate the engine with increased pressure than required. Therefore, know about your engine’s RPM range requirement.
  • Uses: Since you are buying the biggest cam for stock 350, so it is obvious that your engine requires more power for its higher lifts and longer duration. Every ‘big’ cam is different for its size and purpose, which is why it is important to match your engine’s potential and power. Otherwise, the too-big cam can be detrimental to your engine.
  • Valve springs: The valve springs of the cam should fit your engine to ensure better performance. It is one of the most underlying issues that valve springs don’t fit, or they are too weak and prone to breakage. In this case, your engine does not reach the required RMP. If you are buying a high-lift cam, then emphasizing the quality and fitment of the valve springs is important.
