OK i just got married and my wife bought me a 1973 dodge dart swinger and its a pretty car. but it only has a 225 slant six and its auto so first off i would like to put a 360 maybe 340 if can find right price but i also want to make it manual . i know its going take a lot just need to know where to start ? anything will help would be nice to have parts list and what i should switch first. i know im going have get bigger brakes for the size difference and better rear end i just don't what i need or what size of brakes . no clue what i need for any of it. anything would be a big help.
