Want to rebuild one of two motors just dont know which one would be better. I have a 351 roller engine out of a 95 e150 and a 302 out of my mustang as far as after market parts i have 75mm mass air 75mm throttle body tfs track heat intake 30lb injectors gt40 heads mac headers e303 caml. Now i know most of my parts would interchangable minus lower intake but what would give me more power for my money i wanna spend about 3000..Anyone have an opinion on this?
