Strip to Street Help Needed

Hello All,

New member, new to the hobby, first post so go easy but I do need some advice.

I bought a 74 Duster 360 CI bored .040 over W/ TRW forged pistons. Factory rods and crank, " J " heads fully ported W/oversize intake valves, Direct Connection headers, Mopar M1 intake manifold, Holley 600 double pumper, Lunati Voodoo 60404 camshft, TCI-142200 10" Converter, 727 Transmission W/shift kit, 8 3/4 rear end W/ 3.90 gears and a posi carrier.

The price was right, but I'd actually like to tame it down a little and use it more as a driver than the previous owner was going for.

Currently, the car when cold needs to warm up before it can idle, so I spend 5 mins revving the engine up to 2-3K or driving it around the block riding the brake a little. When it does finally idle, it's around 600rpm and lope-y as hell. I'm assuming that I need a milder cam to help out with the idle, but will I have to swap out anything else ? Lifters, push rods ? Any cam suggestions ?

Again, take it easy please.....

Trevor.
