street/strip I wouldn't go over 3K. Just imagine taching er up over 3k from light to light and in traffic. Vigilante 2800 IMO that would be perfect. And remember Vigilante will give you 1 free stall change incase you do more mods or what ever.

 

I believe with a mostly stock LT1 you're wasting useable power that's available down low when you use a high stall speed convertor, and besides you're running out of steam above 5k anyway. I'd stick with the 2800.
