Looks like a Weiand SBC manifold, not sure due to the polishing. The 97 Strombergs have been rebuilt, polished, painted, detailed. Comes with a non progressive linkage. Frog style scoops w/o any filter elements. Purchased this as a rebuilt set up a few years ago but the intended project went a different direction. I have never installed this set up.Comes with a spare 97 carb as a core. Fuel lines need to be completed. $1900.00 plus shipping.
