That must be one of the two versions that Comp Cams makes specifically for the stroker 302 (331/347). I have seen them in Jegs.
With 286 total duration and .598 lift. I still believe that is a lot of lift the that small amount of duration.
However, if it works, it works. Just hope it lasts. With that lift to duration ratio, it can put a big strain on the valves.
