What Cam should I get?

HER1828 .544-lift 218*-228* 114cl 1800-6100rpm -might be more like it with your bottom end.
This is the one I would use in your set up. You could skip the extra stall converter and use it with a higher gear ratio like a 3.91. Ths will work well in the street.

At the track, you could really pick up some time with the proper stall converter.
