Hello all, I'm building a fairly stout 300 going in a old 88 e150, I have a 80 and a 88. I'm curious if anyone has a Econoline with a 300, offenhauser intake like a c series or dual port and a 4 barrel, Edelbrock or Holley. I'd like to hear about any fitment issues or modifications needed to make it fit if possible. It would be a great help, thank you.
