383 cam/ setup help

Hey guy's

Hoping to get some help on my setup with my 69 Dodge D100 (383) . My power doesn't seem to come on till 2800-3000 rpm, then it starts to really go. Thing won't brake stand for nothing, just seems dead down low. Thinking it might have the wrong cam for me. I'm looking for low end/midrange power.

383bb out of a 70 road runner. (Rebuilt not long ago) guessing 30 over
Weiend action plus intake
Flow tech headers
Fast ez Efi
727 auto with Saturday night special converter (1800-2000stall)
Dana 60 3.54 open. Will be adding sure grip

Thinking of maybe going to the Edelbrock performer plus (idle-5500rpm) I'm hoping I can still keep the idle lope I have now. (Guessing the cam now is close to stock specs in the 70 roadrunner)

Thanks for any advice
