Would like to get some more oomph from my 318

Let the torque converter do its job and put more oomph into the torque band.
I always advance my cams 5 degrees with an offset cam key, and enjoy the improved torque, but never go to the strip, either, so I can't say much about effect on ETs.
I do have enough torque for easily controllable wheel slip on takeoff at 1/3 throttle on my 340 with stock converter.
