as the title says...what would it take with awd 5.0? i plan on heads, but what would be best? no nitrous. was thinking motorsport x heads for the smaller ports to keep torque up, but should i be considering more flow like the performers rpms? can i do 13s without a supercharger? if i can get 350 hp (a good h/c/i should do that), calculators say i can, but i assume they are based upon a rear drive and likely a manual trans or high stall automatic.
