Specs Original Camshaft 340 from 1972

The factory almost never published info other than lift and seat duration; that said, from a Crane Cams catalog, listing a Blue print factory replacement hydraulic cam, Crane P/N: 969361:

intake [email protected] 210deg lift.429
exhaust [email protected] 221deg lift.444
lobe separation angle 114 deg

Hope this helps.

That should be about what the cam was in 72. I think the factory listed it as a 268/284
