Idle Quality?

I am just wondering how smooth does this cam idle.
It is in a 6.0L Comp Cam 206-212 Duration @ .050 the lift is 515-522 on a 112 LSA.
Thanks

Small cam for a 6.0 should idle nice and be drivable on a stock verter..

Well it idles rough in my opinion! It idles rough in park but a little smoother in gear. but that is at 670 RPM in gear? Would anyone know how much more fuel should be added at idle?

That cam is tiny it should idle like stock. I have a mid 220s in my 6.0 that you wouldn't even know it wasn't stock if it wasn't for the increased valvetrain and exhaust noise. Idle is at 650.

I've got a bigger cam in my 5.3 that doesn't idle much different than stock (Idles at 680-720). The only thing that I see on yours that might give you a little lope is the 112 LSA.

So your saying you have this cam in your truck already?? That is a small cam.. I guess you have not heard a hard idle cam in one before??

Here's an idle clip of my 5.3 with a 216/220-114LSA cam. Your's should idle smoother than this.

Granted, this was taken with my phone.. so don't expect great sound quality.

That is something your tuner needs to adjust, a straight answer will not suffice without seeing a log of it running. Also, ignition advance plays a big part in idle quality.
