I have a Scott Brown cam in my Challenger and it runs great for being on the small side for my cubes. It was built for a 451 and I reused it in my 499.

I also have a custom Bullet cam in my small block 422 that's in the Dart Sport that also runs low 6's in the 1/8th. The Bullet is pretty big but makes great torque. Both companies made me a great product.
