snowtwister value
D A Z a 1975 merc would be the free-air. from what i seen in the past, a used-condition freeair 440 would bring about $1200. now ad to that a new hood and bellypan and decals a new seat cover, you would be around $1800 to $2000. so i would say for a mint 440 merc would be around $2000 to $2200, maybe slightly more if there is engine mods made.
