i see alot of threads on here about guys trying to break out of the 14s and then look at their mod list and im like wtf. so what does it take to get a 5.0 into the low 13s high 12s. it cant be that hard, i got my gtp into the mid 13s with headers, ported blower, 11 psi, 1.84 rockers, tune and some other small stuff.
