I have yet to see a set of any manifolds that will work, just the 273 man's will. Same as Barracuda, if you can show me or point me in a direction that would be cool Pete .
Might be a good compromise between restrictive early A manifolds and headers.
Ever considered magnum manifold swap?
Just a suggestion.

I am running a 360 , 904, manual steering, I would love to see an old picture or the 360 manifolds that will work if you could point me in that direction Pete, I understand if you can't find anything
Member @Treblig was making magnum manifolds for a-bodies... Not sure if he's still doing it, but he may be able to let you know if the magnum exhaust manifolds may work with an early A body...
