Best starting point for V8 swap

I had already factored in a rebuild with any engine I get (will be my winter project). Budget about 2500.00 (waiting for the dollar to go above par so I can get more for less)!!

I would have thought the 92 would be a little better since in 89 the 360 got the hydraulic roller cam. However there are a few less choices for cam with that yes or no? I will be shooting for about 300 to 350 HP nothing too wild just very steetable.
