OP said stock converter and 3.55' s, and a cam that could possibly hurt his bottom end
I would choose a vacuum secondary like an AVS, Thermoquad, or Holley 750 vac sec
ive run a bigger cam same car 3.23s 27 tall tire stock verter torker door stop and 650 dp 750 would have been better
instant tire smoke if i so wanted
a properly tuned dp is beter then a 1905 edeldog 8 days a week twice on sundays
thermoquad is the only non holley i would use
either you can tune or you cant its not the carb problem
learn how to tune
