thats pretty simple there, without lockup, the converter is still in "stall" (you said it has a 2800 stall converter installed). once the converter clutch comes in, it will drop the rpm down.
also, like ssedan asked, whats the rear gear ratio and tire size as it also play a role in what the rpm will be with lockup engaged.
