a 440 and 727 for $190 is a steal..
putting a 440 into a 74 swinger is cake.. basically a bolt in deal.. the biggest decision is on the headders. some can be expensive. some go through the fenderwells . from the sounds of what you want out of it the schumachers sound good. they are a tri-Y that fit very well with a 440...
if your really worried about the wieght then put a set of eddy heads and an alumn intake ,water pump and housing on it that will take allot of weight off.... if you go with the stock heads just put heavier torsion bars in it and it will handle fine.. that big block darts don't handle except in a straight line os an old myth...
there is nothing like a big block dart.. i say do the 440 and forget about it...
