What tranny for a 318?

I'm rebuilding a 74 dart sport, and I don't know entirely what tranny to use. The car still has the 904 in it, but I've been told to use a 727 by a classic car builder friend.. So the key objective is: everyday driver with some loud, impressive fun behind the pedal. Haha

But ive been told buy a fellow 318 a-body (73 duster) owner/friend, that the 904 is "burly", and that he lit up the town no prob, pitchin it sideways, burnin out, etc. and he indirectly made the point that the 727 is overkill/too burly for a 318. granted his motor was completely stock, with only exhaust, with maybe a 3:75/4:10 or so rear end. Witch is also what I want for my rear end. Posi of course.

Mine is freshly balanced, rebuilt, has an edlebrock wiend manifold, 4 barrel carb, true-er timing chain, after market edlebrock headers (nothin special), but connected to Flowmaster exhaust.. Advice? Experienced words of wisdom from you guys? lol
