In my 78 and 79 catalogue I'm showing a F275/400-8 cam for 273-340-360 and 67-79 318 LA, if that comes close to being what your cam is made to fit. Crane says 275 degrees @.050, 316-316 degrees advertised, 108 centerline on this one though yours appears to be ground on a 104 centerline, .028 hot on intake, .030 hot on exhaust, 0.600 gross valve lift on intake and 0.600 gross valve lift on exhaust also.
