California cars started getting different equipment about that time. Let me pull the 71 TSM... Okay, looks like all 71s w/V-8 and MANUAL TRANSMISSION had the "Air Guard" system, which is an air pump. The pump is connected to the exhaust manifolds and a valve cover through a special valve. If you have an auto trans car all you have is the PCV valve and charcoal cannister, unless it had a 304 from the factory. All California cars and all 304 auto trans cars also used a TCS (Transmission Controlled Spark) system. Those four (Air Guard, PCV, Charcoal Cannister, and TCS) were the only emission systems used in 1971. The early 70s is when emissions really started (68 or 69 for CA), and the systems grew in complexity every year through about 1979 or so. It's easy to get confused as to what was used when under what conditions, as you can see from the previous paragraph! The engine could have been changed, the air pump removed (common, especially if it came from a non-emissions state and the pump locked up), or it could even be a very early production car w/1970 emissions. I doubt it's early production, but look at the door tag at the bottom (unlabeled) number and see. If it's a low number, say under 1000, it could be an early car. That is the sequence the car actually came off the assembly line -- VIN numbers were assigned as the cars were ordered. -------------------- Date: Wed, 16 Jan 2008 14:09:45 -0500 From: "Thomas, Jeff" <jeff.thomas@xxxxxxxx> AMC team, When I bought my car in 2005 I was told the only factory emissions that came with the car was the charcoal cannister which the car has. In looking at the 71 Tech Manual it appears there should be a lot more. Can someone give me a complete list of all the "correct" emissions equipment that were included on a 360 4BBL 4 speed car in 1971 ? The most difficult thing to find would appear to be the log tubes that go on the exhaust manifold. I really hate to try and run this stuff down now but with a complete list I could go ahead and get started. -- Frank Swygert Publisher, "American Motors Cars" Magazine (AMC) For all AMC enthusiasts http://farna.home.att.net/AMC.html (free download available!) _______________________________________________ Amc-list mailing list Amc-list@xxxxxxxxxxxx http://www.amc-list.com/mailman/listinfo/amc-list
