That number is in the GK catalog . It was one of their popular Chevy small-block roller racing cams; 321 degrees duration on the intake and 329 on the exhaust; .660" lift on the intake w/1.65 rockers, and .637" on the exhaust w/1.5 rockers; 108 degrees between lobe centerlines and they recommended .033" lash.
Jenkins ran this cam, or one very similar to it, in some of his 'Gumpy's Toy' cars.
