You're right, Anthony. I used the wrong word. Substitute knowledge for technology. Ford (nor the other manufacturers) knew siamesed cylinders would work. To my knowledge, Chevy was the first to do it on the 400 smallblock. Another thought is how much metal must you have minimum around the siamesed bores for the process to work? Ford could have saved a lot of money by making the cylinder walls thicker. They scrapped a lot of 427 blocks because of core shift and the sand used for the casting was so thin between the bores it wouldn't always stay in place.
