I Passed Smog!
I'm good for another 2 years now. Anyone need a slightly used catalytic converter? 
Seriously, I put a TON of effort into making sure that everything would be fine. I even tested my EGR valve. Truthfully, how many of you even know where your EGR valve is located.
Here are the numbers:
HC CO NO
15 MPH 51 0.23 122
25 MPH 39 0.13 179
Not bad for a more or less stock L81 with 90k miles.
Only negative was that the "Check Engine" light came on briefly on the way home. I've got to get the timing back to 12 or so before it gets unhappy.

I know the feeling. Had to fight it here in CO too. Not as stringent as where you are at though. Had to reinstall smog pump and injectors. Could get by without EGR. You have to have all parts as originally installed (not orignal parts) but all emissions features, right?
Congrats.

He also noticed that I set the timing with the advance plug in (oops) but he let me adjust it to get the pass.

Congrats Mike! Around these parts, seems like every time an older car passes, it's cause for

Did they say anything about your new trans? There was a thread posted earlier about smog and the 200R4 someone was planning on installing in an 80 Vette

He did notice the stall converter though. He thought that my tranny fluid might be low so I promised that I'd check when I got home.
