360 Build for my wife Questions

Hi guys,Need some input on cam,intake and carb choices I have for a 360 build for my wifes duster.All she wants is a "nice sounding mopar and a lil pep to intimidate the mustangs and the import rice cars"..Her words not mine lol.

Some info:
1977 360 rebuilt and bored .30 over
915 "j" heads with 1.88/1.60's
Stock converter and trans
Headman Headers with 2.5 full exhaust with a X-pipe.
8 3/4 rear with 3.23 gears and sure-grip

I was thinking this 600cfm carb from quick fuel..Will 600cfm be enough for street.i don't think the car will see more than 5k rpm's.

For intake I was thinking a Weiand Stealth Intake since basic op range is idel-6800

and for cam I have a brand new mopar purple 340 spec cam in the garge to replace the stock 2bbl .410 lift cam.
