Hi Blue Ox, thanks for reply. Does anyone make a reproduction oil guage for the 6.2? I want to keep the dash looking stock and that diesel oil pressure guage sounds like it would do the trick. I see the senders online but not the guage...
I recently bought an NOS matched 80 psi set - manufactured by Delco.
So yeah, they are out there - and as Derek suggests they were primarily used in diesel applications. But they were also
OEM equipment for Corvettes and several other GM vehicles with gas engines.
Finding them takes a bit of patience and a lot of time on google/ebay. I say "them" because - as you know - you can't use an 80# sender to drive a 60# indicator. Consequently, an 80 pound gauge is necessary as well.
My engine is fairly tight and at start-up - in cold ambient conditions - the oil pressure pegs out high on a 60 # gauge. Even at operating temperature it will still read about 50#. And since I like my gauges to read in the middle of the total range, I recently bought both those parts.
Search using the following GM part numbers:
Sender P/N - 14040816, 06462137, 14039612, 10030966
Gauge P/N - 25025157

There are a lot of unscrupulous people selling 60 psi senders as 80 psi - so before you buy, make sure one of the flats on the nipple is stamped like this:

Just as a guide, I paid $20 for the gauge and maybe $25 for the sender, but I had no big rush and am wicked cheap so I searched for a long time for a good price.
If my remarks above sound a little off, that's because I cut & pasted my post from another thread on this forum:
