need cam advice

motor is a 73 340 rebuilt with 10.5-1 comp. trw .030 over slugs. heads are j heads 915's with 2.02's rocker arms are factory adustables so I will more than likely have to run a mechanical cam and solid lifter. Intake is an edelbrock performer and I will top it off with a 750 holley mech. secondaries. it will be running a 904 auto with 2200+ stall convertor 8 3/4 rear with soon to be 3.91's or 4.10's

I would like a lopey idle with great lower end response. Have been looking at the comp cam series What do ya'll think
