What engine can bolt up to a push button auto Tranny

I am not sure what can bolt up to a Push button tranny. I have a 1972 225 slant six on there now but I think I want a 5.2 on there. basically a 318. I cannot seem to find one or any info that says it will match up. :angry7:
I replaced it with 4 speed stick . I have used both the floor cable shifter as well as push button with same tranny . but like whats already been noted cant use the 225 trans on the v8 . let me know I can hook u up with the trans . Its been sitting for years deffinately needs over hauling but worked when I pulled it out .
