Dakota exhaust manifolds in an A-bdy?

I seem to recall, a few years back, that someone was trying to, or had installed, a set of the '92/93 Dakota exhaust manifolds in an A-bdy. Purportedly, these manifolds flow better than the '68-70 340 Magnum manifolds. Does anyone have any information on this mod?

With the rear dump, I know there are going to be fitment issues, but I sure don't want to keep the original 273 driver's side manifold on my ride.

On a similar topic, when a buddy was finishing his 73' 340 Cuda, he couldn't find an affordable driver's side manifold. He was working in the parts department of a Dodge / Jeep dealer at the time. He ended up using the manifold from (I believe) a Magnum powered Cherokee. Brand new and cheap, well under $70 at the time.

Thnx, Mike in FL
