You have too much hp/torque for the low cost allison transmissions. Much over 300 hp (this changes some with engine rpm and type of application) and the cost rises drastically. A used HT 750 would do it, and might be reasonably priced, but no overdrive. I have never seen any of the newer 400 HP overdrive Allisons for sale used.
