blowing oil out dipstick tube

really twisted my small block crate motor up today; the highest i have ever turned it in first and second gear. when i got back to my shop i noticed smoke coming out from under the front of my duster. raised the hood and it had blown oil all down the passenger side and front of the engine and firewall. the alternator was covered. i assume it blew it out the dipstick. also noticed oil on the bottom of both rear breather caps on both valve covers. don't really understand why it did this? any feedback as to how or why and what caused this would be appreciated. would like to know how to stop this if possible. made a big mess. thanks
