The following is from the 1967 Dodge Truck Shop Manual;
Specifications;
Cooling System
WM-300 7 PSI Pressure Cap
***********************************
In Fact all the trucks listed in the 1967 Shop Manual use a 7 psi cap. My Bumblebee has been running 7psi since I bought it in 2000. My Carryall with original, but recored radiator also runs a 7 psi cap
