Well if u can afford it go with all new stuff or a rebuilt motor. Only get one of the used ones if money is an issue. If money is not an issue get a long block already put together like a 331 or 347. These are questions better for the windsor fourm though. But defenitly make sure u get a 5.0 with mass air. Everything form 89 and up came wiht mass air the speed denstiy was before 89. They will know more about this in the windsor forum. Good luck.
