High oil pressure?

[88 k2500 Alex]

Good morning all, I've got a 1989 K2500 I bought 3 years ago and it's been a solid running truck I've been happy with. It's always had a small leak in the oil adapter seal. Last week I replaced it. After replacing it I noticed my oil pressure running higher. The gauge goes to 60 psi and it will max out when in driving 60 to 65mph before the engine reaches temp then drops back a little after the Thermostat opens. I run 10w30 like the manual says, I just changed the oil and add a qt of Lucas stabilizer. Is it bad to run the truck at/over the 60psi?

I'm pretty sure my truck runs around 60 most of the time as well. I believe that's well within the normal range.

My V6 truck will idle at just under 80psi on cold starts. I wouldn't worry about it. Better than the alternative, that's for sure.

Had a problem like that on my Toyota with a stick oil pressure relief valve, but I'm not aware that that's an issue with most SBCs.

60psi is well within normal operating range outside of idle. Very general rule of thumb is 22psi+10psi per every 1000 rpm.

GM's gauges are not exactly what I would call accurate. But I run around 60 psi most of the time, it will drop to about 30 at idle when warm. Hasn't blown out gaskets or spun a bearing, so I think it is fine

Thank you for the feed back, you've reinforced my original thoughts. I've never had an old truck have such high oil pressure and when it went past the top end of the gauge it had me concerned. I'd read on another forum about a plugged filter, but mine is new, another mentioned the stuck relief valve but in that case the gauge pegged out and stayed there and with my pressure dropping some after warm up I figured that wasn't the case.
