Need some advice on what LSA I want to go with the MS3. Im not sure whether to go with the standard 112 or 114. Concerned about when running the A/C, etc about surging problems. Would the 114 less likely surge or would it not matter after the tune? Thanks.

If you're concerned with surging, and other driveability annoyances I'd look for something smaller. What's your reasoning behind the MS3? If you want a TSP cam, use their 228R/114. That's the ultimate street car cam IMO. Makes power everywhere, with great driveability, doesn't murder springs, and doesn't take forever to tune to get the idle/part throttle right.

Go with a lower LSA since you're at stock compression. This won't bleed off as much cylinder pressure and help give a better torque curve and power peak but at the expense of a lumpier idle (less engine vacuum) You don't need something big like either of the Magic Stick cams. A torquer 2 might get you there, but you should also consider the latest Street Sweeper grind which is either from Ed Curtis or Jay Allen, one of the 2. It's smaller than the T2 but the narrower LSA this helps to achieve very close power numbers.

Go with a narrower LSA since you're at stock compression. The narrower overlap won't bleed off as much cylinder pressure; all of the best performing smaller to medium size cams take this approach. It'll also help broaden the powerband below the curve. You also don't need something big like either of the Magic Stick cams. A torquer 2 might get you there, but you should also consider the Street Sweeper. It's smaller than the T2 but on a narrower LSA.

I want a cam big enough to give me a chance at 400 after the tune, but not surging or dieing at stoplights if im running the A/C.

I would listen to Damian.
What you are asking for (400HP) always involves some kind of driving compromise.
On stock heads you will be somewhat limited by the LS6 Intake. Its a great stock intake, but over ~6300 Rpm's the amount of airflow it can handle really starts to drop off. So over-camming will not work.
You need some overlap to get to that 400HP, but that additional overlap will need some tuning to idle properly. A good 224-228 type cam will get you close to your goal. If you really want that smooth idle and reach those upper Rpm's, I would stick with a 114 LSA.
When you start adding heads and additional compression, you can start manipulating the LSA, overlap, and valve events to really enhance your power band.
Good luck, whichever way you choose.

IMO, Call Geoff at EPS, or TPS about custom cam.
A custom grind doesn't really cost that much more.
