429 engines

[olds34dude]

Hello, I realize that the 429 motors are from an era of idiot lights, but I'm curious if anyone has experience as to the actual oil pressure these motors run in everyday driving, hot with the a/c on in traffic  and down the highway etc.  I know the book calls for 30 lbs., just wonder what the real world driving pressures are. thanks, D. Varney

With 10-40 oil in southern Texas summer I usually see 31#  above 30 MPH, and about 15-20 at idle (hot).
