I just dropped a rebuilt 5.0 motor (-intake) from 1985 gt mustang into a 1989 GT and have 2 Questions : 1:If i go (stock) carbuerated would i still be able to pass smog? 2:and if not the lower intake from the 89 BARELY doesn't line up so would i be able to put heads off an 89 onto a 1985 block ?? I appreciate the help !
