Engle HEV 3945AS Camshaft
I found an old page of a Hughes catalog giving what 496 Polara posted plus "valve lash settings: intake .018"-.020", exhaust .020"-.022". Emailed Hughes but no response. I bought this cam and lifter set many years ago from them with a set of their prepped 302 heads. Box says Engle, grind is Hughes part number. Thanks guys, I get 103 - 104 degrees and 104 - 105 degrees installed centerline.
