What real difference does the lsa on a cam make?

Is this thing fuel injected?

If so, a narrow center will affect the mixture readings big time in the computer.

Stroker is right, narrow means more peakier HP and TQ. High compression will have issues with fuel octane with a narrow center too. I know it sounds funny, but a narrow LSA builds more cylinder pressure.

I like narrow centers, but it's me, and I can tune around them. Stroker is right, for joe blow, 110 is perfect, 114, to me, is just way too far, but if you do have EFI, (i seen it mentioned) unless you build a sim for the 02, or have something re-programmed, not only are you going to have a quick building compression engine, but also a lean running engine, because narrow center cams are stinkier.
