Cam info - HE1423AL

Is anyone using or had used a Hughes HE1423AL camshaft? It's an older camshaft and I couldn't find specs like rpm range and lobe center installation. Glad to hear something about this camshaft. I'm planning to use it with a pair of magnum heads.
thanks!

Not used it but the specs are here http://www.hughesengines.com/TechArticles/6oldercamshaftprofilessmallblockhydraulic.php it's a pretty mild grind but it may be what you're after.
