so i am trying to use my 700r4 in my lt1 swap but am not sure how the lock up is going to work any one have any ideas??

You can get a hydraulic lock up kit that takes all the guesswork out of it...or you can use an electronic kit from lokar or something...p/ns and schematic found elsewhere on this site for a do it yourself kit. It isn't hard to hook up either of them...one, you have to go into the vavle body, the other, just the pan.
