Seat to seat, anyway... I think the .750 roller (R286/500) was 286 @.050 which is still a lot of duration. work
Ran that cam back in the day in our Max Wedge SS/DA car. At the end of each season we had a large box full of broken battleship springs and rocker arms. But man that sucker would run!




I still have two of them on my shelf. One should be sent out for a regrind as I had a lifter go bad.
