Original Temp on 72 SB
I am gong to replace my thermostat but need to know what the original temp setting was in my 72 small block 4sp with A/C. Is it 160 or 180?
Thanks for all the information. This site is great!

looks like only the LT1 came stock with a 180, all others had 195 from the factory. Probably for emissions - I don't think you need to run a 195.

Temp Sending Unit
Shouldn't have to remove the exhaust Manifold. Just have to use a deep reach socket, or an off-set boxed wrench. It's a little tricky, but not a real big problem. I also believe you can get it off from underneath, rather than leaning over the fender on top. Helps to have a hoist. Oh yeah, there are 2 sending units. One in each head.
