I really don't know much about setting up performance engines. My current setup is definitely not ideal. Yours seems to be properly tuned. Anyway, my too big of a cam, low compression 318 has a .484 lift, 284 duration cam that was degreed at 108, per the cam card. I had poor acceleration and throttle response. Mind you, my torque converter was already pushing my vehicle way before the optimum range of the cam. Catalog says 2600-6000 rpm. I advanced the cam 4 degrees (set it up on the triangle). Much better throttle response and low end torque. Don't know if that little tidbit is even relevant to what you are doing but, you said yours was for the street and occasional track.
