what's the correct operating temp

I have a 327 30over - 180f tstat - what should I expect for normal operating temp? I took a ride today and it wnet up to about 210 maybe a little higher - but it stayed right there never climbed higher never dropped lower. Is this right?

Re: what's the correct operating temp

i wouldn't worry about that temp.
after all, water boils at 212 degrees at sea level- at 15psi, it boils at closer to 240ish.

you don't plan sincerity.
you have to make it up on the spot.

wanna hear about 20 years ago when i was too smart to know any better?

I have a 427 .030 over with a 180 stat.My dual flexalites turn on at 200f and off at 185F.Not once did my coolant temp exceed 200F in stop and go thru Royal Oak.Down Woodward the temp hovers around 185F.Unless the 327 is radical..you sound like you need more capacity.If the small block struggles at 75F ambient...summer heat may be an issue for you.

Re: what's the correct operating temp

if its not running close to what thermostat thats in it ,when ambient temp. goes up so will your engine temp..sounds like it might need more cooling capacity[thicker radiator]

Re: what's the correct operating temp

Is the water temp sending unit in the head or is it in the intake manifold? A reading from the head should run higher than a reading from the intake, especially at freeway speeds. Anyone else agree?

Have you verified the gauge reading against an I.R. gun shot of the radiator hose just above the thermostat housing so you know what the gauge is really telling you? You may not have an issue at all.

Nope - there's only about 8" of coolant travel from the head-mounted sender location to the intake-mounted sender location; if there was 2* of difference I'd be surprised.

Re: what's the correct operating temp

Could the thinner cylinder wall be conducting more combustion heat faster into the coolant?

Coolant in a closed system under 15 PSI will boil at 267*F, 3* per 1 PSI.

185 to 195 would be normal
you may have other issues going on ...not enough cooling from the rad may be one .
a good rad good flow and good cfm are keys to cooling .
