P10 = P100 model truck
J = gasoline-powered, 223 cui, 6 cyl, 1 barrel carburetor, 114 HP @ 3600 RPM
H = Assembly plant is Lorain, Ohio
424362 = serial number, assembled in June 1963, 1963 model year.

Do you have the rest of the codes on the data plate?

I'm looking at the different forums here at ford-trucks.com, and I think your P100 belongs on the Large Truck discussion board.

Let me know when the ice cream is ready.
