[Half-Inch Stud]

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

LARGE runners and lacking the choke pad -weird.

P4B-QJ version. I think there are 4 versions of the P4B..

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

Nice pickup Charles. I've been keeping my eyes open for one as well.

Nice Charles!!.. what size are the ports?.. I did end up getting the one above !!

[chuckies76ta]

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..

[chuckies76ta]

Also uses the early style Q-jet bracket..

That is the same exact manifold i have on my car now ! I like it , no complaints about it except that it doesnt have the provisions to mount the later style of throttle/trans linkage . HEI dist fits good with room to turn ,, for awhile there i thought i was the only one with that style of manifold from looking at all the pics of everyone else`s that has posted so far ,,

[grandville455]

Yea I just bought it .... I am going to open it up so i can run my q jet on it... This one appears to have the meat to do that....

Have you done any quarter mile testing with it?

Thanks

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 ,,,

Thanks, I know what you mean, I went into the garage 5 years ago to change the front steering linkage and it turned into a full blown restoration.. And of course lots of dollars..

Well Got most of the grinding done tonight so the q-jet will work on the top... just have to do some minor touch ups.. then its on to opening up the ports some.....

[chuckies76ta]

That one looks pretty much the same as the QJ version. Just will except a 4150..
looks good.
