i figured i may run the 3.5 pulley which according to zzp gives 20hp. but i may not waste time with it and just jump to the 3.4. what else would i need to run the 3.4? do i need the plog or headers? i really didnt want to do headers or the plog. i figured the downpipe and maybe delete/replace the resonator, the intake and maybe a 180 stat might be enough?
