Whiplash cams

I have a 75 duster with the 360 HP engine. Will 1 of these cams pick up the low end power very much. Is ther other ones ground like the whip I will be putting on a Holley street dominator intake as well. Thanks. Kim
The OP mentions picking up the 'low end power' AND using a Holley Street Dominator intake. That intake isn't for low end power, is it?
