One more thing I should point out to all the 300 Ford fans out there. You may have noticed the 1/4" aluminum plate between the oil pump cover and the pump housing. That is one way to make a low-buck high volume oil pump for the 300. The gear and rotor assembly from a 351M/400 V8 Ford are the same size as the 240/300 - only 1/4" thicker. So by taking a gear and rotor assembly from the V8, machining a 1/4" spacer for the 300 pump housing, and installing the V8 rotor assembly in the 300 pump housing you just made a low-buck, hi-volume oil pump for your six!
