I ran the Indy -1 1.5 rockers for over 600 passes with a 278@.050, .660 roller. Found 2 with a crack at the body holding the roller axle. They had a crack on one side only. Then installed Indy 1.6, .705 lift. Never hurt one. They were on the car when I sold it.

I had the same results with the 1.5's on the same cam. Mine were in the car for ten years. Sitting in a box on the shelf now. I went with Harland Sharps the second time around.
Decent rockers with a mild cam. Out of production now though.
