440 cam choice

Ok guys I need some help, my customer is having me build up a 1941 dodge for him, I don't dare call it a "rat rod" as that's not what it is more of a heavily modified custom with an unrestored cab. We are building a new custom chassis, air bag suspension, detailed motor ect running gear will be highly detailed, but the cab will remain unrestored.

Anyway for your help I'm not a big block guy I'm a modern Hemi guy, my customer has requested a 440 (have not purchased the motor as of yet getting it on Sunday) he wants a fairly stock build (power levels are not important) but wants loud (zoomie headers) and in your face I suggested a cam with racecar lope. He smiled and said "HELL YEAH!!!" my problem is finding the nastyist sounding cam possable, vacuum is no concern as it's running manual steering and brakes, it's just gotta have chest pounding in your face attitude. Can you guys reccomend a cam that will fit the bill? As I'm at a loss on the big block stuff. Looking at cam cards tells me nothing about sound. Any vids you guys may have also would be great. Thanks in advance for the help
