wheres the lowend tq...

I don`t see you making a lot of low end torque with a cam like that. Like rumble said the power band probably starts around 3000 rpm. I would make sure the bottom end and valvetrain are stout and begin your low end around 3000 rpm. With such a big cam,converter,and differential gear you should start thinking of low end torque in the 3k range and start working on how high you can rev that engine before power starts to fall off.
