There is a very good site for Ford HP, some very technical HP Gurus at
www.chucko.com
They helped me quite a bit when I was installing my Supercharger. Later,

Curtis, I don't believe any of those cams would give you an honest 475 H.P...you'd probably have to be more in the .050dur 250deg. or more, plus have reworked heads, single plane manifold, headers,750-800CFM carb. etc. Deen
P.S. It's a law of physics...to make so much HP it takes a certain amount of fuel/air to make a given amount of power. You can not make big HP numbers and get good mileage. Those claiming they increased their HP(significantly)and increased their mileage probably did not have their engines dialed in right to begin with.
