Dear Tom: I'll guess it's a carb-heat downpipe. Once the engine is started, heat from the manifold heats-up the carburator, so in cold weather, the engine won't stall immediately after putting it in gear. On a '64 or earlier, there was no emission equipment I am aware of, so there'd be, NO, "EGR". That's one of the beauties of having a '67/older car--not even an air pump until '68. If you have a manual choke, you don't need that manifold-heat down-pipe, because you just put the choke in as the car's running down the road, until, after a few minutes, the carb's warm and it won't stall due to cold. You could use flex-pipe with aluminum furnace duct tape (the metal variety!) to "dummy-one-up" if you think you want one, or if you live in a "snow-belt"/4-season area. An EGR would be on an '80 engine, because catalytic-converters had been in use since '75 on all cars in the USA. Tom, although it wouldn't be stock, the IKA-Kaiser-Renault "Torino", made in Argentina, had a SOHC head that was put on Argentinian Americans that AMC sold to IKA-Kaiser-Renault. Fango drove several in racing in S. America, placed 3rd in class at LeMons one year, and won something in germany. Imho, AMC SHOULD have put that head on ALL AMC 6s because it would have allowed AMC to "carve a nich" in marketing the 6 in-liner, and would have helped their Eagle when it came out. There are probably less than a dozen running "Torinos" of Argentine origin in the US, so having an engine from one, would be a real treat. Some guy was claiming 450Hp from a "Blown & "Grown"(Supercharged, bored & stroked) 232 (3.8L) "Torino" engine, from a Youtube vid from Argentina! That much Hp has been available for decades from 6 cylinder stock cars, that were 3/4 or full-race, so I believe it! mercendarian@xxxxxxxxx ________________________________ From: Thomas Garner <Tgarner@xxxxxxxxxxxxxx> To: AMC List <amc-list@xxxxxxxxxxxx> Sent: Tuesday, April 30, 2013 3:40 PM Subject: [AMC-list] Broken pipe During my 64 232 rebuild, I broke a pipe. I have the intake and exhaust manifold off an 81 AMC Spirit. There is a pipe that runs from the exhaust to the intake. It's a steel according type pipe. I THINK it has someting to do with the EGR valve, but I"m not certain. I can't find it anywhere, BUT I don't know what it's called either so that could be why I"m not finding it. None of the parts guys knows what the "pipe from the intake to the exhaust is or what it's for or called. Anybody know what this is and where I can find one? BTW, nobody seemed to have large enough flare nuts for me to make my own.
