RE: 7 litre Galaxie

The only way to be sure is to pull a head and check the bore and stroke as all 7 Litre VINs will show a 428.

You can check the stroke without removing the head. Get a piece of 12 or 14 gauge house wire and remove the white wire. Get fine tipped magic marker or a pencil. Remove a spark plug. Put the wire in the spark plug hole with wire resting on the top of the piston. If you press lightly down on the wire it should move up and down with the piston when the engine is turned over. Position the wire so it moves vertically with the piston. Set the marker tip against the wire so that it leaves a mark as the piston moves up and down as the engine is turned over.

Measure the mark on the wire. 3.98 is the stroke for the 410 and 428 engines; 3.78 is the stroke for the 390, 406 and 427 engines and 3.5 is the stroke for the 352 and 360 engines.
