Project Big Block 74

The time has come finally got all my rotating assembly and everything collected final assembly starts next week. Details and dyno to come....can't wait!!!
Found out my 727 is a lockup version I don't know much about these but I'm told it won't work. Not sure which direction to head with it now I sure would like an OD trans of some sort not shy of cutting banging and welding. Anybody got any advice or suggestions in that department.
