My opinion:
Original P4B design was a Squarebore-only, with subsequent poor sales, & reputation developed to overlook it. Then Post 64 Picture #2 came out; a half-finished Spreadbore design (does not seal the Q-JET's Primary circuit) Perhaps aimed at the 800Holley Spreadbores, with Squarebore ability. Then Post 64 Picture#1 came out, a finished Spreadbore design, with "Oops, not for Squarebore...'cause we casted a whole bunch of thooose, and they be sitting around. I could be wrong, and would enjoy hearing "the rest of the story" ------------------------------------------------------------ |

Well actually, there were some intermediate ones, although I don't know how you see a qjet anything in pic #2 ??? That is a squarebore only intake.
There was a P4B that had the meat of the qjet flange at all portions but was only machined for a square bore. I don't know if it was large or small runner. |

Found it on Craigslist in Minneapolis
http://minneapolis.craigslist.org/pts/1065233873.html LARGE runners and lacking the choke pad -weird. |

Few pics of the P4B-QJ intake I bought.... This looks to be an excellent intake. The flow should match the RPM..

This is a Felpro1233 gasket comparison. The P4B-QJ ports all measure approx 1.12x 2.03.. The torker 2 measures approx 1.03 x 2.04..
Charles They look as good as the Torker 2..

i thought about doing that too , but there`s alot to cut out for the secondaries and im thinking it will need a spacer afterwards to give the airflow room to turn into the intake, and since there`s not much room now between the air cleaner and underside of the hood on my firebird , the spacer wont allow me to keep my factory ram air hood ,,

no , i havent , i want to ,, but my car isnt road ready yet ,,, not long after i bought the car it was obvious alot of work was needed to keep it on the road ,, and a simple brake job snowballed into ,, " well since im doing this i might as well do that while im at it " ,, kind of thing ,, and then the little side projects started happening and left the car disabled ,, im still working on it to get it back on the road " hopefully " in the next few months ,,,
