Has anyone ever seen this type of simple sandwich type setup(the exchanger part only) for an oil cooler except for a BBC? No oil hoses, no sandwich adaptors, no separate oil cooler. Been looking a lot and cannot spot any.
Sorry this thread would not let me post another actual picture, not sure why so here is the link. This one is from a Toyota Land Cruiser but need one for a BBC.

This would be much much simpler than an adaptor plate/hoses/oil cooler setup, and cheaper, and less weight, and less space taken. I like simplicity.
All i need is about 25 deg of cooling during worse case scenario when the oil is a little over 300 which is not real often - during a wot run only.

Thanks SB. I'll look at these. Spent a couple hours looking for such a thing but never could even spot one that ever existed for a BBC. Go figure.
Hey I see one is far a Ford, so as a last resort, my brother has a milling machine, maybe we could mill the oring area from Ford to fit a Chevy and chevy oil filter LOL.

Probably doesn`t exist for a BBC because it looks like it couldnt cool a lawnmower engine.
Hooked to engine coolant at 212* plus it isnt doing much cooling, almost looks like it was designed to heat the oil , not cool it.

I wouldn’t be trying to reinvent the wheel here. I don’t think our systems are that complicated. Keep in mind too that the cooler, through volume, is meant to keep the oil as cool as possible (within reason). That kind of setup would never be able to keep the oil cool enough in an endurance application.

Seals and gaskets not as heat tolerant as they are now. Mobil 1 was just starting to gain traction. But not totally. The v8’s back then where low hp and didn’t need a whole lot of oil cooling help. The chevy 2500-3500’s, even with sbc’s, in the same time period. ran a oil cooler in the radiator, just like a transmission oil cooler set up.

Here’s a quote from Yellow Bullet with good info about oil temp on a current thread.
Nope, most have oil coolers these days that use engine coolant just like a trans cooler. Warms it quicker and keeps it near the coolant operating temp, which is generally from 90-100°C (195-212°F).
I've been an OEM R&D tech for the last 23 years, did a 6 year stint before that doing OEM work for an outside lab. 35 years ago the marine engines we tested @ WOT rated power and RPM for 200 hrs. would get to 250-280°F without oil coolers. This was dino oil and didn't break down as long as we didn't stay above the 280° mark too long.
I remember one unicorn Hi-Perf BB Chevy that completed the 200 hr test and they decided to run to failure. I dissembled it, measured everything and put it back together with the same parts except gaskets. It went another 200 hrs, rinse and repeat with the inspection. It went another 200 hrs, inspected again, this time the rods weren't exactly round anymore and the bearings were showing signs of fatigue. After all I was taught in school and all that (still more book knowledge than practical experience at this stage) I couldn't believe the thing was still running and they wanted to keep going . It went another 40 or so hrs before it **** the bed, never saw another one get close to that record.
I don't figure your oil broke down either.
