LSA question

Can someone explain a LSA of 113 +2? Does it mean there was 2 degrees of advance ground in the cam? If so, what is the advantage. Cam in question is 228/232 on a 113+2 lsa 588/584

Thanks

I searched and could only come up with 113 LSA before people call me lazy.

you are right, the advance is just built into the cam, i believe its basically a 115 lsa cam.

The seperation between the intake and exhaust is still 113'. The +2 advance enhances the low end power slightly.
