Gen 3 Hemi dual plane.
Also like to point out that folks using carburetors have a very limited selection of manifolds. And with seriously ported heads you will find this manifold makes a solid seal where as the OEM manifold it's a crap shoot at best. I'm very close to running, just waiting on a few more pieces, but this is a very nice manifold that has the promise of doing much better than other alternatives.
