Depends on the stall you get built into the convertor. Mine stalls a bit over 5,000 and I like to launch off the T brake at 4,400. Shift at 6,500, trap at about 7,450. Call your convertor builder, or better yet call several of them and compare their advice. Good luck.

We use a spragless 10" from Trans Specialties. Stalls at 3000-3500 depending on how much boost. We leave from 1200-2000 against the brake. 3450 lbs, best 60' so far under 30 PSI of 1.25 without an anti-roll bar.

We'll see how much it increases with the ARB...
