Are they? Then my apologies. I stand corrected if that's true.

Well, they were when I bought the 60404 that’s in the 340 in my Duster and the 60403 that’s in the 318 for my Dart.

The Lunati’s have faster ramps than the purple cams did, higher lift on similar durations. That would be really tough on a narrower lobe.
