I'm sure I won't be much more than around 430 hp with my 5.7. I do understand there are better transmissions out there but for ease of use/availability/no floor mods necessary is why I'm going with the a833OD. The 4 speed is only going to cost me $150 so can't complain about that! That being said my priority is drivability at highway speeds for this car. I do have a handful of 3rd members in my garage and planned on running 3.23s. Realistically I'll go to the track once or twice a year. I know that is kind of lame but with that gearing I probably won't even make it into OD in the 1/4 mile.:D
