Need help with magnum 360 block 402/435 hp crate motor tech info

My 380 hp create motor has a 2800 stall she goes decent even though I'm under geared with 2.96 which planing to swap in 3.91.

It's a little soft out of the hole but that's probably due to gearing than stall.
I say a 2800 probably work with your car to can't seeing going with too much less.
