That is a tough order. A cam that idles rough due to a lot of valve duration and valve overlap usually does not allow the engine to produce much cylinder pressure and torque a low RPM and therefore you need a lower rear gear ratio to bring the engine RPM up quicker. The rougher the idle, the worst that condition will be.

Sealed Power CS-113R, solid flat tappet cam will fill that request. It would have a bad (meaning good) idle and produce good low end torque and high end horsepower. Cam range is from 2000 to 5500 RPM.

Sealed power CS-113R solid lifter camshaft specifications:
228 degrees I / 230 degree E valve duration
110 deg. LSA
.395" I / .401" E valve lift with 1.5:1 rocker arms
.421" I / .428" E valve lift with 1.6:1 rocker arms (350 CI engine)
Use with 9.5:1 to 10.0:1 static compression ratio.
Comp Cams 813-16 solid lifters
