Help pick stall speed.

[ss dave]

First, got a 383, approx. 425-450 hp, same tq, race built 700r4, 3.73 posi. Burned up the first converter, got new converter but stall too high, approx. 3100-3200. Allowed one converter stall change. This converter warrantied to 1100hp. Can't get tires loose when shiftiing form 1st to 2nd and even difficult in 1st. What would be a good stall for my street ride? Thanks
