Hi Paul,
Your information is correct I'm just wondering why if both cars have the same engine how can one pollute more then the other? Or why one engine needs a air pump and not the other.

I can't answer that question in less than three hours even if I could interpret history correctly. Dave McLellan (Corvette's Chief Engineer 1975-1992) describes the trials and tribulations of emissions in that era in his book, "Corvette from the Inside" (Bentley Publishers, ISBN 0-8376-0859-7, 2002). The juggling act between automatic, four-speed, L-48, and L-82 with respect to federal and CA emissions requirements for the C3 (and beyond) was a nightmare. And one of the reasons that sometimes AIR is there one year and not the next on certain engines with certain transmissions.
Suffice to say, with some interpretation license, that emissions led to the demise of the L-82 with four-speed in 1980, the L-82 in 1981, and the four-speed completely in 1982.
A very interesting read. I recommend it.

Irrespective of the AIR system you still want and need the PCV system and EEC (charcoal canister) system.

Yup have always had the pvc in, will put the canister in next week as I just checked and my mechanic has a used one at his place. Tube is done. That's wild as to the AIR System and the trials and tribulations of the C3 in the 70's and early 80's.

This guy knew his stuff, but I nearly crapped myself when he pulled on some vacuum lines, I just had visions of being under the car on the side of the road in poor light trying to find where to plug them back in. I later found out that they can look but not touch so maybe that is why I was just given a warning and not a ticket. As I said earlier at least I now know and am rectifying it. I still won't head back to Wasaga and go to their annual Wasaga Beach Cruise as it could turn into a massive cash grab for our provincial gov't. The officer told me that they would issue a $365 ticket to anyone who has a breather on instead of running the tube into the air cleaner. Most every vintage corvette that I have seen at this event (expected well over 1000 vettes) has a breather on it.

You have too many cops in Canada if that's how they are spending their time. Reduce police forces by 20% and see how many smog pumps Barney Fife goes sniffing around.
I just hate it when people with uniforms start quoting rules is rules crap.

Yea, it's getting to be a cash grab for anything now, with so many municipalities going broke. While haven't seen any emission enforcement around here, sure are a lots of cops issuing speeding tickets. They're getting tricky too. Driving home on the freeway the other day, saw what looked like a silver construction pick up in the median. Passing by, saw it had light gray police stickers on the side you could hardly notice.

Makes me think that photo radar will be making a big comeback, as that had proved to be a huge cash grab up here a number of years ago. Could you imagine if they set the gun to go off at just 1 or 2 kph/mph?

Well if you dont have emissions testing in your area than consider yourself fortunate. We have them here in the Phx AZ valley. My 72 is a non smog engine, so it does not have the pump. The block code tells you if the engine was equipped with the smog pump. My original engine is being overhauled now, its getting a considerable upgrade. Emissions must be tested all the way back to 1967 vehicles here. But....... there are exceptions which I am looking into. A coworker restored a 73 Charger, he said by putting collector car insurance on it he has been able to license it without testing. I have to take my truck down for testing next week, I'll be asking them for the straight scoop. My 92 corvette passes easily, it has 130k on it.

only cali sold cars required injectors, canada didnt require till 75. correct me if i'm wrong 
canadian law allows a car to be built to what was on the option list for that car of that year. thats why i scooped a 74 vette rather then a newer, 74 had the 454 on its option list... i'm legal to upgrade lol
