Getting conflicting info on the correct manifolds on a 71 Duster 340. Can anyone confirm what the correct casting #’s are? Thanks
 
Left 68-71 A body 340 is #2863553
Right 71-73 A body 340 is #3418623

Good thing I bought $100 worth of books so I could share this information. :poke::lol:
 
Intake or exhaust manifolds? Your initial question is ambiguous.
 
I'm not an English major, or a math major, but he used plural, so I assumed exhaust manifolds. All in jest, so don't everbody get your nighties in a knot.
 
I can pull my 1970 Swinger 340 EXHAUST manifolds out and take a picture of them, if that would help. Just as soon as I untwist my nighty.....Never mind, I just saw he said 1971. Different animal than 1970.

You can always count on nighties gettin in knots around here.
 
Those casting numbers match my 1970 Swinger 340, but I can't find a date coded nighty from Our early married days. It looks like the dog ate 'em. Some kind of dog.....
