Nah they were warm

If you can hold your hand on them they are only 130* or less.

I get that but I have stats on a bracket spaced out also, after run today I will use my temp pointer on it to see, I guess maybe could be an issue

I was curious what you found with your oil pressure issue?

Bypassed stats seems better as it dropped once for a split second, thencame back but I will have 4 more 90's in system to remove

This oil filter has a 3/4" threaded nipple. Standard equipment on GM engines uses a 13/16" threaded nipple. Might be a flow restriction for big blocks.

I ran Hardin Marine's for the last 4 years or so - part #625-7703 for IV's and 7704 for 5&6 blocks. Liked its simplicity, location, and the fact that it probably flows really
well with it's 3/4" NPT ports. Worked great as far as flow and thermostatic control - Oil temps stayed up through my longest 6mph zones, and for the first time ever high oil temps were never a concern no matter how hard I ran,, or for how long - sucked because I couldn't get the washered bolt up through the unit to stop dripping oil. Washer's seemed too hard. like copper instead of brass?. Even tried valve lapping compound to lap the parts together - lived with it in the end, and apparently Hardin has since changed something, not sure what, since they had a lot of complaints when they first came out, and price is lower now. I am no longer using it, partially for that reason, but more so because it puts 4 large AN fittings between my oil pan and the top of my stringer, and is a PIA to get those lines on/off to pull motor, even though only two have to be removed - just two tight in that area on my boat. A remote unit will leave only two fittings there, and at a better angle. Twin engine setup may not have that issue.

This is the one I have chosen so far - like the overall design and large 12AN ports... when it is open to the cooler, it is WTFO They come in 215 or 185 temps (as well as even lower temps) I think I am ordering the 215.

A little off the subject but what are most using for the block adapters. I've used the canton or morosos but wouldn't mind changing to something with side ports.

These have always gotten the job done but...

This is what I'm running, zero issues with pressure, but they are big and bulky. These are Keith Eickert's, I'm pretty sure they are not made any longer, but they work great.
