Just wanted everyone's opinion on the 15511; I already have this cam but still having to decide between this one and the Comp Cams hr264; I like the specs on both and I'm still indecisive..also I'm running EGR delete with GT40P heads and wanted to make sure it doesn't have any drivability issues. I don't plan on going back in to her after that but I'm thinking of eventually supercharging with a MSPNP. Any comments or criticism will be appreciated.
