Where can I find camshaft specs for my truck?

[Silverado4x4]

Mines a 86 silverado with a 305 4-speed. I was just wondering what the specs on the camshaft were. /forums/images/graemlins/thinking.gif

They're so bad that GM doesn't want you to know... /forums/images/graemlins/wink.gif

The biggest problem with most stock cams is that they barely open the valves. /forums/images/graemlins/frown.gif
