good call Cinder!
the Chevy big block the exhaust ports are equal distance from each other and on the small block they have the two center ports right together.
that's a small block Chevy going into that Camaro. the vavle covers are another dead give-away.
the cubic inch displacement of the enging doesn't dictate it being a big block or small block. the engine design does.
