My temp went from a little over mid way TO just getting over 100 degrees about 1/8". I love it Nice and cool ALL the time. I wonder whats going to happen in a few months when it's a 100 outside.

Be prepared for your mileage to go down, carbon to build up, sludge in your pvc and premature bearing failure...
just kidding.. but those are some of the tendencies of motors running too cold... combustion chambers, oil, etc are all MUCH more efficient at higher temps...

yep, theres a reason that most OE thermos are 185*-195*. Motors run more efficient in the 200-210* range.
I didn't bother bringing up the EFI aspect, as I know he's carbed....
oil temp gauges reveal some interesting things... I never had one till last year and the new info and tendencies, are welcome info...

I've run a variety of thermostats on BBC/SBC engines and have found that 160 is generally too cold for good atomization in the manifold. I prefer 180/195. If there is an issue running hotter than the thermostat rating than inspection/repair of the cooling system is warranted.
x2. With a good cooling system, engine temp should never raise above ambient with unrestricted coolant flow. Not getting into the no t-stat argument.
If you put a 160 in, and it doesn't run that warm, your t-stat is faulty. My car with no t-stat also ran at 100*.

And if you are using the factory gauge there is nothing to say they are accurate.

I think 160 stat is too cold. A cold engine is not good. Its Ok if you are drag racing and need to keep the engine cool to make the most HP. But in a truck or car 160 is not an ideal temp to run. Bad gas milage, increased engine wear and other problems discussed above. Occur in an engine operated too cold.
Generaly 350s and most other older engines run most efficiently with a 180-195* stat. Newer engines are designed to run even hotter.

If you can pop the cap after running for 15 minutes with little to no pressure, and can stick your finger in the coolant without getting hurt, the gauge is close enough.
