After 13 minutes of run time on the test stand, we had a failure of 2 springs.Cam was a .480 lift with 1.5 rockers.These are definitely not the springs you want on your engine.

These springs were installed on a 307 SBC T-Bucket show car. Driven less than 5 miles, and have broke 3 springs in 2 weeks. Definitely not worth the savings or the Headaches.
