340 mount pictures----Please

Ah its like no way the mounts go on front of the ears. Seems it has to be the back

Can the trans slip a 1/4-1/2 inch backwards causing the engine to need a good pull forward?

Darn hoist I rented today was leaking oil and gave out early. Using my floor jack to lift the short block now. Yeah I stick the heavy heads on after its bolted it. I'm a little guy working by myself so try to make things easier / lighter.
