As far as bolt up, I have in the back of my mind that modern trannys fit 1963 sixes and up and 1955 V8 and up. In your case, There probably will be a bell housing/flywheel change or an adapter needed. As Bill indicates, Auto? Manual? what are these proposed trannys? Anything is possible and has been done already. You only need time, space, a little help and money. Many bolters here know the tricks once they know what you have and what you want specifically:(motor/tranny).
