Bootybandit Posted July 4 Author Share Posted July 4 So what your saying is that I shouldnt use a port on the Carb I should use the Manifold? I did do what you said to get a vacuum to the little tree located on the body near the hood, I used a 1/8 NPT connection. Oh and the kick down arm is in the shop I havent installed yet as Im fighting other things atm. Link to comment Share on other sites More sharing options...
ArdWrknTrk Posted July 4 Share Posted July 4 it is more important for the pcv to go to as common of a vacuum point as possible as to make all cylinders draw pcv equally. for example, if it were on one single runner, that cylinder would get a lean charge as it would be pulling pcv vapors instead. the brake booster is different as it does not flow anything (unless it's bad being a vacuum leak) it can go to a vacuum tree as long as its big enough port for the hose. This became a huge issue in early EFI Mustangs. I think it was #7, would eat so much oil that it would diesel and blow away the crown down to the ring lands, aasssnd away you go! Relocating this to a new bung in the plenum 'fixed' the problem, but it should never have happened. Link to comment Share on other sites More sharing options...

The "little tree" is a vacuum manifold for the climate control and the speed control. 1/8 should be enough, because these operate on potential, not volume. The booster needs volume, and a functional check valve. Usually it is the center sprue of a vacuum tree located in one of the rear runners, like #7 or 8 depending on the manufacturer. Speaking of.... what manifold do you actually have? Link to comment Share on other sites More sharing options...

Speaking of.... what manifold do you actually have? I will buy a tree. They're surprisingly expensive. I cant find anything to identify the manifold. I do know that its a summit and I bought in combo with the holley 4160 (which they recommended) that's gone now. But I now have a new more pressing problem. The cheap AutoZone reman starter I just bought is just spinning. I moved the crank by hand a few times but it makes a weak attempt to engage and then just spins free as a bird. The lady at AutoZone told me not buy that junk but its the only one that fits between these dang headers. Other people I have spoke to recommended a High torque mini. It worked for a little while but slowly started making more and more noise until its death. I wrapped the poor fellow in a blanket and wrapped the headers to no avail :( Link to comment Share on other sites More sharing options...

It is the last of the 302 Windsor powered ones. If it is a manual, get one for a 1994 F series 300/302/351 manual transmission. These are PMGR (Permanent Magnet Gear Reduction) units and are smaller physically that the old "rat trap" moveable pole piece ones. Get a good reflective heat shield for it and leave some space for air circulation. If Gary, Jim and I can all crank a hot 460 with one of these, there is no reason it won't spin a 351W easily.

Its an automatic, are the Lincoln ones smaller than normal? It needs to be smaller to fit in-between the headers (stupid things). I had to take the cover off the solenoid just to get it in and then went insane trying to put it back on lol. Link to comment Share on other sites More sharing options...

Did you look at the application chart? 🤔 All Windsor bell pattern trucks take the same starter. Well, you need to differentiate between manual or automatic, because the engagement depth is different for a flywheel than a flexplate... Link to comment Share on other sites More sharing options...
