Title: Temp Range and Oil Pressure Question 401
Post by: Rbear571 on July 26, 2009, 09:36:22 PM

I have a '65 GS 401 4 speed.  It has Stewart/Warner aftermarket gauges for the temp. and oil pressure.  The car runs about 215 degrees and 30 PSI oil pressure (being generous in the oil pressure) at 60-70 MPH.  Is that a normal range because I am not a GM guy at all, that temp. / oil pressure range scares the hell outta me. I am trying to learn all I can about these motors but theres not enough guys at the few shows that I attend to answer my questions.  The motor never knocks and has run in this range since the time it was rebuilt without an issue. The engine was rebuilt about 5 years ago and has about 5,000 miles on it.  Thanks for your time and the site.
