Mounting an engine crossmember in a 59?

[Caveman49]

Looking for some opinions, thoughts, whatever, on the following....
I'm using the bolt in engine crossmember on a stock 59 frame and would like to hear from you folks with the experience. First pic is of the 350 engine sitting on the crossmember, second pic is of the crossmember resting at the bottom of the inner frame (the position of crossmember with engine pic), and the third pic is with it in the center of the frame.
What I'd like to know is, which position would be the best to bolt it in, the bottom of the frame, or the center, or if it even matters? The only benefit I can see at this point for center frame, is it'll give me more clearance from the front frame where the harmonic pulley is located............thoughts, suggestions would be much appreciated. Thanks, Lee
