I don't recall the open pressure off the top of my head but anyone can do quick math if they wish for a rough ball park. I topped them off with a set of 1.65 harland sharps.

I broke it in just like that with 1.65 rockers and didn't bother removing the inner springs. All went just fine and that engine still runs perfect to this day.

Don't know why you guys are having so many problems.

I threw a 2802 with the cheap Summit brand lifters in my 455 last summer, also with 68404 springs but 1.5 rockers. I pulled the inner springs for break-in, and while I like to think it helped, it likely wouldn't have mattered. Runs great! I didn't know people were having issues with Summit cams.

I would like to see what kind of oil people are running when they experience a cam failure. I haven't lost an FT cam yet, but I always run a proper break in oil like Lucas. How many cam failures are due to running a cheap oil with an additive rather than a proper non detergent break in oil?
