I need a 390 hp cam for my '66 427, does anyone have the specs for this cam? does GM still have this cam? Or is there an aftermarket cam with the same specs?

The cam was GM #3883986. It was discontinued from SERVICE in August, 1999. However, a Crane-manufactured reproduction is available under GM #12364055. This is a kit which includes camshaft and lifters and it GM lists for about $182. It's a very good value, especially if you buy it at a discounted price.In Appreciation of John Hinckley- Top
