<div>Adding washers is an old trick to adjust the oil pressure relief.  Should see 75 -80 lbs or so when cold and 60-65 running hot at high RPM. </div>

Amici,<br>
<br>
Interesting discovery when I disassembled a spare racing short block.<br>
<br>
2 hand ground washers at the end of the oil pressure relief valve shaft.<br>
<br>
Clearly meaning to increase relief pressure. The washers are different thicknesses, suggesting Doug had a specific relief pressure in mind...<br>
<br>
Cheers!<br>
