Need A Little help Please

I'd be looking into converter,i run a 4.10 with my 28 tall tire shift @ 6600 and am hitting 2nd by 100' or less you need to get that stall up.You will prob want more gear as well for 1/8 mile but you need to get into that power range right at the hit and keep it there.My flash is prob about 5k and drops back to 5800 on the shifts but i'm only 6600rpm shift.
