Mal, that is a 27 Model T touring with a 29 Model A frame and grill shell. I took 2" out of the grill shell. It also has a 48 AB8 Flathead and 3-spd overdrive Merc tranny. You can also see in the background my 288 52 packard and my Sun engine anayler and a murray pedal car. The dash is the one out of the 55 clipper And that is only the right side of the shop haha!

If you decide to go 374", I have a complete rotating assembly: matched 374" pistons, new rings, rods, re-ground crank and front balance damper - everything race-balanced. I can set it up with a manual shift flywheel, clutch and pressure plate if you want to go that way. PM me and we can figure shipping.

I am not a engineer, but the pump design has issues. The shaft connecting it to the distributor is a 2 piece design with a collar. The shaft is only supported at one place, and it is just a cast support, not a bushed support. You can just imagine the spinning and wallowing out of this area. A good place for air to enter the oiling system.

Some pumps had 2 places for support, when the vacuum pump was on the fuel pump. The PI fix was based on this idea.

The fix that Bob Aller used was to install a bushing in the top cast area, and a new lower shaft. He built a testing plate with a place for a gauge to test the pressure.

I believe this is how Terrill machine repairs the pumps as well.

The problems with the original oil pump and "other people's fixes" are extensively discussed on this website and elsewhere. They are moot in this case.
