I see 165-170*. Gained ~8-10psi of oil pressure everywhere which tells me it's staying cooler.

Brian, that's invalid info. You have a rebuilt motor with new bearings in there. You can't actually say just thermostats alone increased your oil pressure. You have too many other things changed to say that's viable

I have no problems with the racing thermostats. Drives fine. It does heat up much quicker under wot. Could be thermostats could be block fill but probably both. It cools off within a few seconds as well. No negative comments. Do not expect any miracle experiences when using them. It one step along the way to help g the engine produce. Its probably not going to measure a statistic to justify buying them if that us what you guys are looking for as answers. I like mine but then I did not have a problem with stock ones either.

I saw an increase of 10-15psi with these in mine and my dads truck.

Kinda thinking outloud here.

But shouldn't these help lower the trans temps 5ish degrees as well once the truck is warmed up, due to the cooler in the radiator?

Should also take longer for the trans to warm up as well

Installed these the other day, I don't have an oil temp gauge on my engine but i'm seeing coolant temps around 168-172F and oil psi at idle is up probably 2-4psi.

So far I'm happy, especially with how easy they are to change out.
