I wouldnt buy anything you have to instantly drop a motor in, because the car was prolly ragged on thats why the motor blew, then you have to find a motor to go into it and you dont know what could be wrong with that motor. And even if nothing is wrong with it if your swapping in a used motor you need to do all the maitnece things on it while its out of the car so that would prolly put you very close if not over your budget depending on what motor your getting and what maitence you do to it.
