That's a rare block... Ford built very few of them with this hole. It was used to sense crankcase blowby pressure, in order to regulate heavy blower applications in race cars. :roll:

Seriously, it's where the road draught tube hooks up. The bolt holes are a mystery, but the long metal pipe that hangs down, is what belongs there. It provides crankcase ventilation. After some years, it was plugged off, and a PCV valve fitted to the valve cover instead. You can do this, too if you wish. Just fit a brass plug in the hole with some Permatex #3, and use a later valve cover with PCV.

Regards, Adam.

The block from my 64 doesn't have the bolt holes and the block from my 65 does. The 64 has the vent tube and 65 is plugged and has a pcv connection in the valve cover. Doen't look like the bolt holes were ever used for anything.
