Scored me an Offy!
Glad to see someone willing to go the four barrel route. The only other consideration I had was a Super 6 manifold with a Weber DGV carb. I liked the idea of not having to be running both barrels all of the time.
So what did I do? I checked out the Holley 4150, 390 cfm. By itself, it wasn't enough to get me to commit. Then I found this. Had to have it. OK, I spent a bit more for it than I would have paid for an Offy or Weiand. But this was too cool for me.
