Default LS-3 Engines

Are the LS-3 engines in the Grand Sport manual transmission vehicles hand assembled? Someone told me that this is so. I thought that none of the LS-3 engines were hand assembled.
Thank You

Non GS owners are a little touchy about the Hand Built Dry Sump motors.
Best we don't talk about these motors in front of others. If you show the Dyno results, you will be poo poo'd off the Forum.
So just take your fat, heavy, areo challenged GS and park away from the narrow, light, super fast C-6's. Don't look back at them. They all think you wasted $5K on a wanna-be ZO6 with a wimpy motor.
Enjoy your new car in private and find some new GS friends.
Put me on your "Friend" list.

Not to nitpick, but it's LS3 (without the hyphen).

There all "hand assembled", just depends on what your definition of that means. No extra horsepower with the GS LS3.

No jealousy here. I pick my cars like I picked my wife. Performance, not looks. OMG, I hope she never sees this.
