i am very new to eprom burning. I kind of don't know what to change when the information from the eprom is extracted with a programmer is this info called a bin file. after this what is next in line to do. I have ran winaldl and logged some data at idle and have downloaded tunerpro. As far as mods I have just a cam swap

----------
oh by the way this is the cam. I have a 305 tbi motor

For a SD system the first place to start is the VE table(s). These will change when a cam change is made. You can use the BLM data to update the VE tables with better values.

See the sticky Tuning Guide Book, there are a couple of articles on the TBI VE tables.
