    Dual quad intake ports? Parts?

     



    I'm installing a Ford factory low riser dual quad intake on my 390. The large port in the rear had this basket that slid down in it and was stuffed with some kind of rolled up wire mesh. No cap on it though.

    This is a joke, right ? If not, put the wrench down, and back away from it. Sell it to me for 10 bucks, and smile...

    I'll raise the bid to $12-------back in the early 60s I got a new one from HolmonMoody with the carbs and linkage delivered air express for $206.00

    That was kind of expensive back then. Before 1966, when I went in the service, I was only making 120.00 a week. .

    Bill, He didn't put this in the joke section. If your serious, I have detailed info on those intakes.

    Denny, I've learned that the rear opening is for a "road draft tube" Never heard of such a thing. I'm going to use it for PCV but I was wondering if I could tee fit it and also use it for power brake booster.

    No. I have to dig up some info for you. From the front of the intake back to the rear, that is for PCV. The brake booster has to get vac from the main source at the rear of the base of the carb, where the vacuum is the greatest. The one at the rear is to pull engine blowby gases from the crankcase. (negative pressure). You do not want oil getting into the brake booster.


    This is a good way to do it, by using the balance tube, and blocking off the rear breather. That's what I did on my 410, and never had a problem. Make sure you use the hard, non collapsing vacuum hose, and the correct PCV. This way it splits any crankcase fumes more evenly and not from one spot.

    Here's a pic from a Ford manual showing PCV location.

    You'll also have to put a closed breather on the oil filler tube. If not done properly it will build up so much pressure in the crankcase that it can blow the dipstick out. Been there, done that.

    Hopefully, he will show the valve covers, and breather. I just wanted to show the tube hookup first.
    Ken, if you notice the picture I showed him, it has a PCV in the valve cover, which would give the crankcase a negative pressure.
    ps: Sorry Ken, I was really tired yesterday. I reread things this morning, and yes, you are correct on the closed breather where the PCV sets. That link I showed him, also has them listed there if he doesn't have one already. Or, he can use a twist in there to hold the PCV.

    I was referring to the oil filler tube in the first picture.

    Well, that one has been removed or something. No longer shows. Anyway, hopefully he will show some more before he decides on what all to use.
