Exhaust manifolds, no numbers

I saw one post in the ads where it was mentioned that the ones without casting numbers were for T/A and AAR. That's just not true. There were no special bins for exhaust manifolds at the factory for a 6 pack engine. They all came out of the same lots. The reason the numbers are not clean and clear are from mold wear. Nothing more.

T/A and AAR had the same exact exhaust manifolds as the 340 Swingers and Duster for 1970. #'s 2863549, 2863553

Someone came up with a story at one time to JACK a buyer for more cash. That's my opinion.

You have 68-70 A and E body 340 exhaust manifolds. They are desirable pieces.
