need some advice

hi guys I have two motors that I am looking at getting one is from a 68 dart but we dont know what it is 273 or 318 the other is a 318 from a 93 dodge van I know that the 93 would be a better option but I dont know if I can get an intake to work on that motor and I dont know what it would cost to make it work. I can get the dart motor for pretty cheap and its alot closer to home I need som help so lets hear it

thanks shiifty
