In "Santucci Speak," a 292 is a heavy duty tall deck (HD/TD) and the 230,250s are standard duty low decks (Std/LD). He deliberatly does not use the manufacturer's cubic inch designations because most hotrodders enlarge the bore, creating a larger displacement. So a 292 L6 bored .030 over is actually 296 CID, .060 = 301, .080 = 304, .090 = 306, .100 = 307, .125 = 311. But if you went into a parts store and asked for stuff for a '296' you will get either the wrong part or a puzzled look.
