Scrap,
I seem to recall that somewhere on a web site there are specs for that marine cam. If I remember right it is more duration and lift than the stock car cam but not as good as any of the currently offered 260 degree hydraulic grinds available. About 4 years ago when I was planning my 250 I researched everyplace I could think of and came upon that cam. I'm sorry I don't recall exactly where I found it but I know for sure that after running the numbers I decided against it for my particular engine.
