Default Re: Eab

It really just refers to the new part number of the cylinder heads. In those years the Mercury had EAC prefix heads. The Ford EAB prefix heads have a good compression ratio if a person wants to use stock heads for a street motor. The Mercury heads generally have a lower ratio to work with the larger displacement.
