Lobe separation angle?
one other ? Providing the cam duration and lift are the same, what differences would a cam with 112 LSA and one with 114 LSA be?, which one would have more lope, driveability issues, etc?. (running a 6spd) Thanks

Lobe separation angle is the number of degrees separating the peak lift point of the exhaust lobe and the peak point of the intake lobe. I'm running a 112 LSA on my MN6 and the lope is more pronounced than on a larger LSA cam such as the 114 you mention. The smaller the LSA, the more overlap in the valve events and the more negative effects on emissions. A smaller LSA tends to shift the power peak down in the RPM band.
You can see how the LSA comes into play in the intake-exhaust valve event interaction in the illustration below.

I want the rougher idle
