O_D --- The 21st Series shop manual calls for 50 lbs for the 356 engine, and 40 lbs for the 282s, measured at the fitting. Thinking about it, the difference in pressure between the circuit that supplies the hydraulic lifters and the one supplying the rest of the engine, as measured by separate gauges, must be due to them being on separate circuits. The original electric dash oil pressure gauge is connected to the lifter-filter circuit. I was thinking about installing a thin shim under the pressure relief valve spring to boost the pressure a bit. What thickness would you recommend, .050-.060"? Thanks.
