This is very true .Also an FE 332-428 [Except 427 SOHC]is easy to identify as they all use the Inlet Manifold to form part of the head on each side of the engine.[i.e Underneath the Valve Covers , the Pushrods actually pass through the Intake]. 429-460 Do not do this. Here is a listing of some other Ford FE Big Block Engines.... Truck-331,361,391 Passenger-332,352,390,406,410,427,428.....There may even been some more available in the Lincoln-Mercury Range that I have missed....I think there may also be a 430 c.i. FE Lincoln Engine ??? Hard to tell them appart but some people can , not me.
