is a cast iron, oval port intake #3866948 (holly) the correct intake for a 360hp 66 BB chevelle?

My Hollander book says the cast iron number for the holly BB should be ..3966948
Two different types of cast-iron intakes were used from 1964 to 1967. graemlins/beers.gif

Maybe that 3966948 is a printing error. As far as I know, #3866948 is the Holley intake. It was used for 1966 and 1967 350 and 360 hp cars.
