Canadian Carbured Emissions - Carburetors - Third Generation F-Body Message Boards

Apeiron · 02-10-2005, 01:57 AM

I've been looking in some old dealer brochures lately, and I've noticed some interesting things with respect to the availability of the CCC system on Canadian cars.

The 2.8L 2bbl V6 LC1 was not available with CCC.

The 5.0L 4bbl V8 LG4 was non-CCC, with CCC being available at extra cost on Sport Coupes only. It was unavailable on the Berlinetta and Z28.

The 5.0L 4bbl V8 L69 was only available with CCC.

A CCC LG4 will also have RPO <b>NB1 - Emission System, Closed Loop</b>, instead of NM4 - Emission Control, Non Closed Loop (Export). Both of them should also have NM5 - Emission System, Canadian Requirements.

A friend at work has an 83 Firebird LG4 with CCC (vin H). My wife's 83 T/A does not have CCC (vin H).

I'll have to dig up the documentation and dealer order sheets for my 1983 Z28... Mine was factory ordered and I'm pretty sure that the CCC system could be ordered on all LG4 cars that came to Canada though very few were optioned that way.

I remember the salesman talking about it... and talking us out of this option...

I dug out my old Canadian Dealer books and
The CCC option WAS avalible on all LG4 engines in Canada in 1982 and 1983 (PRO code NBI) it was an extra cost option, did not increase performance and was rarely (if ever) ordered
