Getting true oil pressure reading

[Dino]

My stock oil pressure gauge reads only around 30 psi, regardless of rpm.  It's probably the gauge itself and I'm not really worried about the reading on this gauge but I do need to rule out any actual problems so I need to find true oil pressure.  What's the easiest and most economical way to do this?  Get the HF oil pressure gauge?  I don't want to buy an aftermarket gauge because I don't want to use one, I just need to test the pressure. I'll recalibrate or replace the stock gauge next year.

That's something I've lived with as well.  I had a couple of times when the my oil gauge just said ZERO and it freaked me out so I had my shop verify the pressure externally.  I'm guessing they hooked up a gauge into where the sender sits?  The only thing I see us doing is replacing or restoring the gauge.  We can't keep playing this guessing game...

You will probably need to get a cheap aftermarket mechanical guage and plug it in there temporarily.

This is going to be hard to beat with a 20% off coupon, but the accuracy may be a bit off as well.  Any budget gauges out there that would beat this?

I put a mechanical one in mine mounted under the dash and it read 15 pounds higher than the stock one.

Where on the 440 engine is the oil pressure sender located?

Back of the block on the top where the bell housing  bolts to engine........ I put a "T" in the port so I could keep my factory gauge in the dash and mounted a mechanical gauge under the hood so I can see what true oil pressure is. Best of both worlds.

there are 2 oil pressure ports in the back on a big block....I never trust the stock gauges, I got mechanical oil and water gauges under the dash on my cars

I found the 2nd port to be a different size. But yes, you are right, there are two ports, one on each side of the web.

found the two oil pressure ports, thanks for that tip. 

if we ever get spark, I intend to fire this engine up.
