hughes whiplash cam and other cam opinions

Years ago, we put a Crower 271 HDP in my younger brothers 70 road runner 440 with 6 pack pistons and it was a great cam. We didn't go too large because of the power brakes. It had a little chop at idle, but still loads of torque. We didn't dyno it, but it would burn tires with ease. It would probably also work well in a 383 and probably have a little more chop at idle. Crower #32242. It's usually a good idea to install any cam about 2 degrees ahead of spec to compensate for initial chain stretch.
