Every flat tappet cam ive broken in seemed to lope more after it was run for a while. Where is your timing? Sounds like your motor is laboring, and at a high idle too. Im guessing you are running manifolds as well?
now that I'm on my computer and I listened to the original video, I agree.
Tune the motor. idle sounds like it's up at about 1000-1200 rpm. dial it back to 750 and see what you get then. if it won't idle that low, find out why...timing off? idle mixture off? vacuum leaks?
Tune, tune and tune some more! I have a Whiplash cam in my 383. At first it was OK performance wise, had a nice rumpity idle and would "bark" the tires from a stop. I was happy with it, but...kept messing with the tune. Now I have it where it will flat blow the 275/60R15 off from a standing start if I'm not careful. And that's just stepping on the go peddle, no burnout or nothing like that. The ol' 383 runs dang strong now, right on up to 6000 RPM. Idles at 750 RPM. Hughes came up with a nice street cam.
