An interesting observation I'd like to share. I had this engine on my test stand for a while, making sure the carburation and ignition systems were working correctly and also to develop the 6 volt tachometer driver we make. The stand has quality mechanical gauges on it, and I got quite familiar with their readings under a lot of conditions. The stock oil pressure gauge in the car seems to be spot on with the one on the stand. Hot idle is about 25 on the stand and a bit above the one quarter mark (20 lbs) in the car. At 2000 RPM, I have 55 on the stand and part way between one half and three quarters in the car. It's a little different with the temperature gauge. 160 on the mechanical is a little over half scale on the car gauge, while 180 is three quarters scale on the car. It's all relative, because the car gauge just has "C" and "H"; it just seems it runs a little high to me.
