Motor help

[cdail28590]

When I got my 28 Bertram the previous owner had put in 1 new 350 crate vortec motor that makes 310hp. The other motor was the standard 350 260hp motor. He made up the hp difference in the props. I have pulled both motors and am planning to upgrade the 260 hp to a 310 hp motor. I have the heads and intake but I am wondering about the cam. Does anybody know the specs on a 260 hp cam and the 310 hp vortec cam so I can compare the two? Also the 260hp motor had a wedge under the carb to allow the carb to sit more level. I guess it was around a 10-12 degree angle wedge. The 310 motor doesn't have any type of wedge. Does anybody know if I need this for both motors or where to get it from? Any help would be appreciated.
