Nope, I've got the book and know it well. I guess this was in part my earlier point. A stock Ford Galaxie side oiler was not a 500HP engine, not even close. Only with aluminum heads, 2x4 carbs, higher compression and your coveted camshaft could Shelby get 505HP. Now of course someone will come along here shortly and say that 505 was really 600.
So, if I Doug or I want a solid 500 HP on a legitimate dyno we need at LEAST stage 2 heads and possibly a compression bump.
