degreeing small block cam

Argh! Just got the 360 running in my 72 Swinger, but it starts very hard, and I can't get the thing to run/idle quite like it's supposed to. I bought a purple cam and just installed it with the dots. I played with the timing as much as I could, and it made it driveable, but something is definitely very wrong. Does anyone have a good link on the entire process of degreeing a cam? I think it will solve my problems by the sounds of it! Please help I'm desperate!!:help:
