40Ford what kind of valespring life do you get at that RPM?




After talking with a few comp guys, they have told me that when your spinning these motors at full tilt, you can get about 6 passes on a set of springs. Also, i don't want to make it sound like 10K is just that easy, but rather it is possible to achieve and be efficient in comparison to other engines spinning that much rpm. In a SS/AM application, you wouldn't run the motor quite as hard so you could probably expect much more spring life at a lower rpm. I would imagine the fatigue life of a spring at over 10K vs. that at 9500 and below are very different.
