Where's the Wow?

It was a new converter but I didn't get one ordered. It was a 360 high torque from Pat Blair. So probably not ideal but don't think I'd lose that much from it. Really not much power up top either. Should have mentioned when I put it in gear at 900 rpm it engages hard and kinda puts the car "up on its toes" but almost stalls down to 450 to 500 rpm
