Stop wasting your money on thottle bodies and the like.
There have been a number of people experimenting with bolting on on PI intakes to NPI heads lately.

This is the one that started it all: Modified PI intake to stock PI heads: Must read for comparison pics on Page 2

Then this adapter set came out (very nice work I might add) :

Well, some people got the talking and figured that nobody had bolted up a unmodified PIintake to a NPI motor and dyno tested it. There is a slight diffence in the shape of the ports so the intake and head ports don't exactly match up, but it seems for a N/A street motor, it didn't matter. The bigger runners of the PI intake still made a big improvement in power:
Direct bolt on, unmodified PI intake w/ dyno results, not tuned
This goes further to show that very little extra power comes from the stock PI heads, good flow numbers or not. Most of of the gains in the 99+ motors come from the cams and intake.
So what are you waiting for, find a used PI intake and get yourself some seat of the pants power.
