We looked up the OE turdmostat for a '75 C10 Y-code SBC, and it was the 195 degree unit. Replaced it today and went for a ride, and no change. Still climbing up to 210 and hovering there (I haven't wanted to push it to see if it will go further).
So, options? Get the radiator "cored" (is that the right term) and see if it needs a good cleaning? Replace the radiator? Or look at the block?
