Camshaft Idle/ Selection SBC 350

[franknitticutlass]

Would there be a noticeable idle difference between these 2 cams?
SUMMIT 1103-Advertised Duration 272/282, Lift .442/.465-112 degrees lobe sep.
SUMMIT 1104-Advertised Duration 282/282, Lift .465/.465-114 degrees lobe sep.

If so which one would be rougher and/or best for a sbc 350 with edelbrock intake & edelbrock 600 carb?

well the 112 lobe center cam would probly idle a little ruffer but the 114 lobe center cam has more lift and duration with the lobe center opened up it would blead off less compression so i would guess the 114 lobe center cam. but the 112 lobe center cam might make more top end power
