I would write down all your questions about trans/engines and find some drag race guys
at the track....but not bug them when they are really busy.

Next choice would be to find a shop that works on them and ask if they would recommend
a mopar performance book that includes engine/trans combinations. Some of them may
require new motor mounts. The dealer might also have a performance book.
I know that both Ford and Chevy have them.

Third would be to go by LKQ, pay the $3 admission and ask for an interchange.
They print out the combinations of what will fit certain engines/trans for certain years.
