Dont know how it would happen but just check to make sure oil pressure sending unit wasn't damaged or disconnected. When oil pressure whent to zip did the motor start knocking/ticking etc?

did you do anything to the stock oil pump? Usually this happens if the o ring on the oil pump wasnt put on right or something else with the oil pump.

How many miles where on the oil pump thats in there? Sounds to me either something wasnt installed right or the oil pump died.. one reason most replace those when they swap cams. Some dont and they get by fine, but the added strain of the cam can kill some pumps that have miles on them

Did you take the stock oil pump off at all during the install? If so, you might have accidentally installed the o-ring incorrectly. I would just tear it apart again and make sure everything is installed properly, better safe than sorry.

Other thoughts:

Does it have oil?
Did you use air to install valve springs? I did and the chain put a hole in the oil pump...was rather a freak thing but could happen to somebody else.
