the tranny woes

[Lightspeed]

ive thought and thought and rethought about what kinda tranny id like to keep in my 67 stang and i just cant figure it out...i just finished saving up enough money to get my motor rebuilt and found some pretty killer package deals to give me about 350 horses which is what i was aiming for out of my 289, i wanted to go with the t5 tranny swap at first but it seems to be a bit complicated and so i rethought my steps..then i wanted a toploader 4 speed because it would bolt up..then i decided to keep the 3 speed thats in it but ive changed my mind again...im not really all that sure of what all trannys will fit and which one is best for me. so the bottom line is what all transmissions are a pretty much bolt in job that will fit in my stang? id apprecaite any feedback, thanks
