without motor & trans i'd say i'm at about $2500-$3000 so far.
90% of that has been worked out through trade & i got my motor & trans for practically nothing by time i sold the car & parts it was being swapped into.
for my motor & trans package i would expect to pay up to $3000 alone for what i have, 02 LS1 w/ LS6 intake, & 4l60e with only 45k on it.
after i sold the car the motor was being put in i'm about $300 out of pocket for it.
my suggestion is be patient, shop around & do a LOT of research.
