I don't think you'll find a level off of less that 1000'. AMS is the lowest I know at 1500'. If you're at easy the standard acceleration is 1000'. If you're single engine then it's first stop alt, no level acceleration before or MSA so your question isn't relevant. The speed commanded will be dependent on whether there is a speed constraint. If no constraint then see DSC 22 30-80-40 p 3/4 where it says:
The SRS law maintains the current speed at Go-around engagement, or VAPP, whichever is higher. Nevertheless, the SRS speed target is limited to VLS+25 kt, in a two-engine configuration, and VLS+15 kt, in an engine-out configuration. When the SRS mode disengages, the target speed becomes Green Dot speed.
