Help with cam choice for magnum 360 please

I've heard alot of good things about the ebay grinds, with that being said I don't have any experience with them personally.

On another note did you consider any of the MP cam's? Like they use in the 360/408 crate motors, there are 3 or 4 different ones from stock to max lift(501/510).

thats what I'm using in my magnum....just a thought, sorry just to jump in.
