The stock lower is the real problem in the stock induction system. The upper average flows in the mid 190cfm range by itself with good flow balance but add the lower and that falls to mid 130s average with poor flow balance. The heads flow 160cfm on the intake side. See info below - and notice that you have to multiply the shown values by a 1.06 correction factor.
I can port that lower for you so that the stock intake flows in the 180cfm range for $100 + shipping - typically $125-140 total.
Hey 88workcar - I got the new MM&FF mag yesterday and there is a car painted same color as yours in there.
