440 motor mounts

Well I still have not received the engines I bought so I'm still sitting here on this. Moving the mounts on the k frame is a no go as stated above so I guess I am going to make my own motor plate/elephant ears. Any odd ball measurments I'd need to know to do this or just bolt the trans down and fab the engine up where I want it? Or is the engine gonna be offset to a side or the other? It's going in the drag car so I think I'm gonna drop it in there and mount it as far back on the tranny mount as I can unless there is something that's gonna make me do it differently. Planning on running fenderwell headers just don't have them yet and no kick down cable and an aftermarket shifter with a cable.
