Default gas fauled plugs?

I just got to putting a rebuilt lt1 in my 91 chev pickup. The motor is out of a 95 camaro it has a 97 computer. I have an aftermarket harness. The motor is stock but has a gm performance cam. I don't know which one. I was told the biggest. It does have stock programming on the comp. I also have a new mass air. I fired the truck and ran it for about 20 minutes. after 15 the truck was not wanting to idle on its own. I tried starting it the next day and had no luck. I pulled the plugs out and they are gas fauled. I tried cleaning them with a lighter and sand paper and it started for a few seconds then died. I'll go get some new plugs in a couple days but I was woundering if anyone could point me in the direction to look for why the gas fauled.

are you sure?
cause if you have a big ole cam and stock injectors and a stock tune there is no reason for it to be fouling out. Now if you had a stock tune and bigger injectors it would be dumping gas like crazy and that would be your problem

With a stock tune and a bigger cam, you're going to run rich. What plugs, and what gap?

I put new plugs in it and the truck fired right up. Now I have a few more things to fix on it and we'll see if it kills another set.
