years ago I ran one on a stockish magnum 383. The car had more low end grunt by virtue of how it would spin the tires off idle with a stock intake and 3.23's than it did with the SD and 3.91's. Same car, same tires, same road for both set ups. I also have both b and rb versions on the shelf, saving them for strokers with stock hoods if the day ever comes.
it is nice that the runners allow all stock accessories to mount up.
