Found an old Weiand Manifold for a 440 Anyone seen one before, has a huge bowl like appendage under it all cast in no add on.
Has part No 7512.

ok , can you get a couple more pics of the manifold from the side and top . it looks like a team"g" manifold but the numbers dont match any current mopar manifold ( latest model is a 7533). most of the weiand manifolds with a 75 number seem to be team "G" the only exception seems to be the x-celerator series manifolds and these arn't available for the big mopar. i will do some more diging but im sure somone on here will beat me to it .

Trev, Its definately not a team G as it has no team G stampings or embossing.
All the runners are smooth and there are no other markings on the manifold and it has not been polished or ground anywhere and a sharp turn at the end of the runners

Its a very late 60s early 70s im told ??

Looks like a Weiand X-celerator to me, similar to an Edelbrock torker or a Holley street dominator perfomance wise.

whilst i cant see for sure, the 'large bowl bit cast in' that you mention is either a heat crossover, or it is a dual plane manifold.

Blue its not an X celerator, and Hugh its definately not a Dual plane, that bowl underneath is huge and has a boss for tapping into it for some reason, I will try and get a better shot in a day or two, just wondered what its operating range might be and is it better than a street dominator which is wicked for B / RB street strip motor
