Edelbrock 318/360

looking at an Edelbrock manifold stamped 318/360 will this fit a 1966 273? i know the 273 and 318 manifolds inter change 1966 and up. just trying to figure this out. I need a little help I am afraid the 318/360 ports are a little bigger than i need.

Do t worry about port size. The intake will fit. The 64/65-273 has the odd bolt angle and size.
