360 Magnum cam recommendation

What cam would you recommend for a 1999 360 magnum going in a 1974 duster with 727 trans, factory high stall converter, 3.21 rear gears. Going with a 650 Holley carb, headers, 2.5 exhaust. Cam will be a roller regrind from Oregon cams or Delta cams. I like good low end torque with 5500 rpm redline. Smooth idle is fine. Thanks.
