Here are the 2 cams from GM. I would stay with the GM intake its better than the Edelbrock. Get a Good Holly carb for it,
If you can afford it get one with annular booster's for response.

This hydraulic flat tappet "502" is a good street high-performance and marine cam used in the Gen V 502 H.O. engine P/N 10185085.
