440 cam help

Looks like that 484 lift P4120235AE does not start making power until 2200 rpm and up to 6000 rpm. This cam is like #4 on their Hydraulic chart. Most people put too much cam in their cars for the street, then there is no power there on the low end when taking off from the stop lights, no vacuum for power brakes either, poor idle. Got to use a high stall converters to get them going.

The first hydraulic cam is more like the Roadrunner Cam with good performance and driveability.
P4529270AE Idle to 5800 rpm
The second hydraulic cam is a step up.
P4286677AE 1300 to 5700 rpm
