lack of smog equipment functioning and the loss of the weight of the cast iron manifolds (and no smog) had to help the 427 right out of the gate. Great article. Actually I don't see a belt on the smog pump in that one picture, so maybe the smog was not working after all. Neat that the 427 version was 50 lbs lighter than the others. Had that cool hood on the 427 that I would think could be doing something to help that carb get more air too. And is lighter.
