I broke my engine
You are correct. The rear ones would just throw a code (sorry). It's the front 2 that need to be bad in order to make the car run rich. I remember after I did my header install my car ran so rich it filed out the front O2's and was making the car run bad. I replaced them and got a tune and everything was fine.. Sorry about the mix up! What I said about washing out the rings is true, it happened to a friend of mine after doing the same thing. Now he has a 402ci in the car because of his mistake.. Not a bad deal if you ask me, unless you can't afford to rebuild the motor if you mess up..
LOL...at least your honest! You will find being cheap and taking shortcuts will only lead to more costly problems. Some people you can tell this to and others learn the hard way.
Good luck on the car fix!
It should be a sticky some where that when you do it yourself, if you cant afford to do it right, you cant afford to do it. Taking short cuts never works out for the best, and makes it much harder to track down whats going on. You need to take it to a reputable tuner to find out whats going on. It could be as simple as the tune, but who knows what you may have screwed up.

Blue smoke! You washed your rings out from driving it arround while its running way too rich. I hope im wrong, but it sounds like a rebuild is in your near future. -GET IT TUNED BEFORE YOU DRIVE IT ANY MORE- And change your oil now! I'm sure its black as coal.

This is interesting...because I have a 86' Z28 that did something similar! I found that the throttle cable was f'ed up and then I set the idle down lower...no probs now, except it still smokes, but I have completely forged 355 sitting on an engine stand waiting to go in. lol 
As for your case, def need tune, do leak test and etc. However, I hope you learned something out of this...if you don't have the money to do the job right...wait til you can bro. lol I know it's tempting to put a cam in these V8 Ls1's but you gotta be safe...especially if it's your DD. Best of luck!

Guys, you are missing the BLUE smoke...that is OIL, not fuel. Fuel is black, blue is oil, and white is water (most times). He is burning oil, whether it be rings, valve seals, guides, etc.....
First thing is first, we know he needs a tune cuz of the cam, fine.
BUT, more importantly, with the blue smoke, he has bigger issue's that need to be addressed.
So, was your car fine before the swap? No smoke? Little smoke? How many miles on motor? Etc... If everything was fine BEFORE, we need to look at what you did do, what you didn't do. With teh cam swap, you swap springs? If so, you replace valve seals? Reuse the old ones? Possibly damage a couple/few/one? We need to start there.....
How many miles have you driven it since the swap? I would say very little, and if that being the case, you did not wash the rings.

NO mtter how many times it's said, people NEVER listen. CHEAP IS NEVER THE WAY TO GO.
I'm also courious if you checked piston to valve clearance. The blue smoke would bother me more than the running like crap.

Same here. Kinda freaked me out the first time it did it.
k got a bunch of questions to answer ill see how many i can get
ive only driven it about 100 miles
it is blue smoke but it smells horribly like fuel (kinda did before though lol)
the biggest problem is that i really cant drive it anywhere to get it tuned or get the exhaust done so i gotta wait for a friends trailer.. and i leave in 2 weeks for fort benning...so its just gonna be in storage for awhile anyways.
thanks for all of the help though guys....

Ok, only 100 miles, you did not wash the rings. Blue smoke with fuel smell, more than likely:
Burning oil (bad valve seal possibly) AND running rich (lack of proper tune).
Now, in your PM, you told me you reused the old valve seals. How many miles are on them? I would think that we are looking in the right area for your problems. At this point I would:
Since you can't drive it or take it anywhere, go ahead and pull the VC's off, go ahead and replace your Valve seals.
Get her back together, fire it up, and see if that fixed your "blue smoke' problem. If it did, great, then you can proceed with the tune and exhaust.
If not, then we can start loking at other things, but I would do the tune/finish exhaust first. Why? Hard to find a problem with open exhaust and the car running like crap.
Good luck

I always thought blue smoke was fuel burning, but maybe i cant tell the difference in blue and black smoke. My old 72 ford had a rebuilt 390 in it and smoked like a freight train with the old carb (ran really really rich), and it was blue smoke. Got a new carb and adjusted it and it quit smoking.
