I am looking for the stock cam specs for a 1968 dodge charger 440.

Mopar Perf. lists a resto cam #p4452783: 228/241 @0.050", 115 centerline (is this the lobe sep angle??), .450/.458" lift.
Comp Cams lists a "factory id" cam #21-305-4: 222/226 @0.050", 110 lobe sep angle, .464/.464 lift.

Does anyone know what the real stock cam specs are for this engine or where to possibly find it? One would think this info would be available somewhere. Thanks a bunch!!
