Drag: Have motor and trans, but which car?

Well, I showed my add for the 74 dart swinger to my dad today, i also went to google images and showed him what they looked like. He liked it but suggested that i should get something like that challenger, i have $1500, not $4500, and its not even for sale anymore. Chargers and Challengers are crazy expensive even without motor and trans. All I want is something to have fun with and work on though...Ill have enough money for it monday, so i will ask again then :)
