Marine cams cost $350 through marine parts distributors. * Here is one for $115 from Comp Cams who are one of the best cam grinders out there:

As an added benefit, you'll make roughly 275-290hp over 260 if you use a stock intake and heads. *Summit has house brand marine cams for as little as $52, their advertised durations are a little long, though.

I really don't believe a special cam grind is used in the marine small blocks. The lift numbers between automotive and marine are the same, but I haven't found the duration and LSA for the marine cam, yet. I'll be you they are the same as well, making the cams identical.
