stock 5.0 roller cam specs

Hello, What are the factory 5.0 roller cam specs. I know the lift is supposed to be .444, but what about the duration? I haven't messed with a stock cam in awhile and have forgot. Thanks

Early cams were advertised @ 266/266 until August of 88 when they went to 276/266. Doesn't matter much, when F/S allowed only stock shafts lots of them were cam doctored and the duration @ .050" varied in the general envelope of 204-212 degrees in duration. THAT is significant. The lsa and ICL varied too. They vary from lobe to lobe too. My HO cam is at the high end of those specs and makes pretty decent power for a stock cam.
