<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>
